WEBVTT 00:00.120 --> 00:06.480 OK, now we're going to look at the visualizations in more detail, starting with graphs and more specifically, 00:06.480 --> 00:07.830 time series graphs. 00:07.860 --> 00:11.490 There are many ways to stall your graph at all. 00:11.940 --> 00:17.370 Essentially, they are graphs showing time series data now, time series data. 00:17.880 --> 00:25.290 If I look at one of these, for example, inspect the data consists of a timestamp and a value. 00:25.350 --> 00:27.620 So it's just time stamps values. 00:27.630 --> 00:33.150 That's time series data and behind each and every single one of these graphs is something like that 00:33.150 --> 00:35.230 a series of times with a value. 00:35.250 --> 00:38.310 That's what we're seeing here, and perhaps even multiple time series. 00:38.340 --> 00:44.250 So for this one, there is one two three four five different sets of time series data that behind this 00:44.250 --> 00:45.120 particular graph. 00:45.870 --> 00:50.040 Anyway, in your copy of Carafano, I'm on my copy of Credit. 00:50.070 --> 00:54.620 Go to dashboard's ménage and we'll just create a new dashboard. 00:55.050 --> 00:56.370 Add an empty panel. 00:56.400 --> 01:02.580 OK, so by default, it's using our default data source, which we've selected as standard DB with one 01:02.580 --> 01:04.890 time series being random walk. 01:05.100 --> 01:11.040 And that's a default graph, so we can refresh that, and it's random walks are changing every single 01:11.040 --> 01:11.370 time. 01:12.000 --> 01:14.480 OK, so test data DB is good for learning. 01:14.490 --> 01:15.450 It's just like data. 01:15.510 --> 01:19.290 Now, if we look at the scenario, there are many scenarios in there. 01:19.320 --> 01:24.890 Not all of those are going to return time series data that can be shown in a graph like that. 01:24.900 --> 01:30.930 But the ones we can use random walk, random walk with error, which is the same as Random Walk, actually 01:30.930 --> 01:34.600 shows some error information if you wanted to see how that works. 01:34.620 --> 01:40.470 We could also use one called says the metric values, which are hardcoded values. 01:40.470 --> 01:45.810 So if you look at that, that's one 2090, etc. that the numbers down there, we can change. 01:45.810 --> 01:49.640 Those could make that a 10, and it updates the graph dramatically. 01:49.650 --> 01:52.530 Or I could make it a hundred or I could even add. 01:53.670 --> 01:56.220 For example, that's six feet metric values. 01:56.280 --> 01:58.410 That's a good option for testing. 01:58.710 --> 02:01.230 And also another one called streaming client. 02:02.430 --> 02:05.460 So streaming client is continually updating data. 02:05.550 --> 02:10.200 You can sort of see that being drawn there, but we'll zoom in to it so that we can see that, but also 02:10.200 --> 02:13.680 just highlight with the amass a section and zooming into it. 02:13.680 --> 02:16.110 Now we go, it's just updating continually. 02:16.140 --> 02:17.220 That's the streaming client. 02:17.310 --> 02:22.980 So you can use those scenarios inside the graph visualization to help you when you're working on your 02:22.980 --> 02:23.640 graph style. 02:23.760 --> 02:30.510 Now also, as well as zooming using the mouse option like that, you can use this dropdown here to select 02:30.510 --> 02:32.250 a certain time range sample. 02:32.250 --> 02:39.690 Last five minutes ago, I could see the last five minutes within that range or specific times now minus 02:39.690 --> 02:42.750 five minutes to now or from that date to that date. 02:43.410 --> 02:46.690 But it's just easier to get to the last five minutes, perhaps. 02:46.740 --> 02:53.820 OK, so I'm going to go back to just random walk for now and look at the different options that we can 02:53.820 --> 02:54.960 use to store that graph. 02:55.290 --> 03:03.090 So on the right here, panel options this top dropdown in previous versions of Safana, the option to 03:03.090 --> 03:08.370 choose your visualization was part of one of the options in this section here. 03:08.400 --> 03:12.600 It's now being moved right to the top, so the first one, which is the most common you'll see is Code 03:12.600 --> 03:15.240 Time Series, which is basically the time series graph. 03:15.420 --> 03:21.360 If you're more familiar with version seven or less of Gravano, you still have an all graph visualization 03:21.360 --> 03:22.320 here that you can use. 03:22.470 --> 03:28.050 I'll show you time series option, so that's what we have selected already time series and these are 03:28.050 --> 03:29.810 the options for time series. 03:29.820 --> 03:32.080 If I change that, we'll get different options. 03:32.130 --> 03:34.800 For example, state timeline, we get different options. 03:35.770 --> 03:37.080 I go back to time series. 03:37.200 --> 03:37.500 We go. 03:37.530 --> 03:39.900 So here title, I can write anything. 03:39.900 --> 03:45.670 I like my panel title and it's updated there, and if I went out, it would save my panel title. 03:45.690 --> 03:50.220 Now, in the previous videos, I changed that title by using the panel. 03:50.220 --> 03:50.880 Jason, there. 03:50.910 --> 03:51.990 That's a little more complicated. 03:51.990 --> 03:55.380 It's actually easier just to use the edit option there and change it there. 03:55.530 --> 04:02.250 My panel title description if you like ABCD and that will show up here the eye, if you wanted to, 04:02.250 --> 04:04.560 to help your users a little more understand what's going on. 04:04.590 --> 04:09.750 Transparent background OK, so takes away that greatness panel links. 04:09.750 --> 04:11.400 We can add a specific link. 04:11.700 --> 04:17.850 For example, I can show any links I like that are more descriptive for the graph, for example, my 04:17.850 --> 04:18.390 website. 04:20.630 --> 04:28.400 And open a new tab if I wanted to save and that will then show up top left their website shows my grandfather 04:28.400 --> 04:29.150 on new page. 04:29.390 --> 04:33.980 Whatever you are you think is important, I don't need that repeat options. 04:34.100 --> 04:37.430 This is a more advanced subject, will come onto this later. 04:37.460 --> 04:39.300 There are no template variables found. 04:39.320 --> 04:42.380 We'll look at template variables later on in the course. 04:42.380 --> 04:45.950 Template variables are useful for dynamically creating graphs. 04:47.050 --> 04:52.990 Tooltip when I hover over parts of the graph, you see that shows the date and I series seventy seven 04:52.990 --> 04:55.690 point two, then seventy four point four. 04:55.720 --> 04:57.340 That's the tooltip at the moment. 04:57.340 --> 05:03.280 I only have one series available, so we're only seeing one single time series in a tooltip, so all 05:03.280 --> 05:06.200 doesn't have any effect and hidden just hides it. 05:06.520 --> 05:13.090 But in order to see all have an effect, I'll add a second time series down here by pressing query. 05:13.090 --> 05:17.640 So be I have a new time series called B, and I'm also going to use random walk. 05:17.740 --> 05:19.120 That's good already. 05:20.930 --> 05:23.750 If it doesn't show up, just disable and then enable again. 05:24.110 --> 05:29.900 So I'm saying to time series update now, I could have also just pressed Refresh on the dashboard to 05:29.900 --> 05:30.290 show it. 05:30.410 --> 05:36.570 OK, so going back to tooltip mode single is just showing whatever the closest value is. 05:36.590 --> 05:42.560 So based series a series, if I press all it will just show both all the time I Series B series and 05:42.560 --> 05:43.730 a Series B series. 05:44.540 --> 05:50.410 OK, so legend the legend down here is that the left Stiefel list table? 05:50.420 --> 05:55.820 OK, so it's now in rows or hidden placement bottom or right? 05:56.600 --> 05:57.920 OK, OK. 05:58.070 --> 06:04.700 And Legend Values We only have two things written there a series and B series, but we can also. 06:05.660 --> 06:07.700 Share more options, so last. 06:07.880 --> 06:15.230 OK, so I'm showing the last first max value, there's quite a lot of values to show their distinct 06:15.230 --> 06:15.680 account. 06:17.110 --> 06:19.930 Last, first Macs lost, first Macs. 06:19.950 --> 06:27.030 So if we show the Letterman placement on the right, perhaps more easy or even as table on the right 06:27.150 --> 06:27.810 or the bottom. 06:28.840 --> 06:29.650 There were options. 06:31.000 --> 06:32.110 Graf Styles. 06:33.210 --> 06:38.380 So we can draw our lines at a particular store, so this will be more obvious if I zoom in to a section, 06:38.380 --> 06:42.540 so I'm going to zoom in to the, well, let me zoom in further than that. 06:42.540 --> 06:49.500 So I'm going to use this now minus one minute at a time range and then change that. 06:49.590 --> 06:51.580 Still not that obvious. 06:51.600 --> 06:54.790 So now minus one second. 06:55.470 --> 06:58.020 It's not that obvious on this particular graph. 06:58.110 --> 07:02.050 If I use CSP metric values, that will be easier. 07:02.070 --> 07:08.640 So down here for series, I'm going to use CSP metric values and just use those default numbers. 07:08.640 --> 07:09.100 Excuse me? 07:09.120 --> 07:12.360 OK, so I go, that's straight line between each point. 07:12.930 --> 07:16.700 Curved stepped and stepped differently. 07:16.710 --> 07:24.600 So the first one, the point is positioned there like that, and that one is the adults in a different 07:24.600 --> 07:26.400 spot line, which. 07:27.730 --> 07:35.050 Feel opacity, so the area below the line, for example, gradient mode opacity, it fights out a hue. 07:36.350 --> 07:39.800 And a scheme so scheme we can sit further on down. 07:40.400 --> 07:41.330 I'll come back to that. 07:41.390 --> 07:49.280 Right now, it's just a rainbow colour is opacity line style, solid dashed dots. 07:50.630 --> 07:53.010 I can use Dashte Connect null values. 07:53.460 --> 07:59.640 This is best when the time series data doesn't return any value for a particular time, with the time 07:59.640 --> 08:00.670 stamp still exists. 08:00.720 --> 08:05.520 For example, the time series might return that, and you can see here that there's something missing 08:05.520 --> 08:08.280 in the middle there, or it might even be now. 08:08.310 --> 08:13.890 Same thing, since this is random walk is just regenerating random values or Series B, I'm just going 08:13.890 --> 08:15.030 to delete that for now. 08:15.030 --> 08:16.610 So it's less confusing. 08:16.620 --> 08:17.140 Let me go. 08:17.220 --> 08:18.360 Just refresh that. 08:18.480 --> 08:23.220 OK, so once again, now it could be nothing. 08:23.220 --> 08:23.700 Or now. 08:23.760 --> 08:29.820 OK, so connecting null values always case that the value is now connected, even though there's a null 08:29.820 --> 08:30.420 in between. 08:31.020 --> 08:37.050 So it's never or threshold, so it only connects when there's a certain time period. 08:37.060 --> 08:43.450 So let's say one hour, let's try one minute now, let's try one second one millisecond. 08:43.770 --> 08:47.040 Guess so the time difference is less than one millisecond. 08:47.040 --> 08:51.750 So let me join the dots if the time between those two points is less than one millisecond, if I can 08:51.750 --> 08:54.420 say always or never or even put that back. 08:54.540 --> 08:55.800 OK, show points. 08:55.800 --> 08:57.900 Always, never, always the point. 08:57.900 --> 08:59.790 Stick and see the circles or never. 09:00.840 --> 09:05.190 When you hover over the point and you have the tooltip enabled endpoint size, very large. 09:06.900 --> 09:11.610 Stacked series, this is about whether you have multiple time series, so for this, I'm going to put 09:11.610 --> 09:14.400 that back to random walk. 09:16.180 --> 09:20.920 Incredible series, but instead of creating a query or sitting random walk, I'm going to duplicate. 09:21.190 --> 09:25.390 OK, so I've got to now be a and be refreshed that OK, so they're both there. 09:26.550 --> 09:30.150 OK, so Steck series is off normal. 09:30.930 --> 09:36.120 The two values have been added together, so if you look at the tooltip, a series equals eight nine 09:36.120 --> 09:36.690 point five. 09:36.690 --> 09:38.700 B series equals thirty eight point three. 09:38.730 --> 09:42.240 Together, they total just a little bit less than one hundred and thirty. 09:42.240 --> 09:50.370 There they are stacked on stacked, so showing the real value stacked or within 100 per cent. So 100 09:50.370 --> 09:51.870 per cent so off. 09:52.870 --> 09:55.610 I think we have stylus access. 09:56.180 --> 10:01.850 Access is automatically positioned on the left like so or I could have it on the right as my access 10:01.850 --> 10:03.680 on the right or hidden, it's no longer there. 10:04.040 --> 10:06.160 Auto optional text. 10:06.170 --> 10:14.570 I can have anything I like ABC, ABC that's just describing what the access means with auto or I could 10:14.570 --> 10:15.320 hardcoded. 10:15.950 --> 10:16.520 Let me go. 10:17.420 --> 10:21.170 Just auto is easiest soft meaning soft max. 10:21.170 --> 10:22.680 Not sure what they are anyway. 10:22.700 --> 10:24.830 Show grid lines on or off. 10:24.950 --> 10:32.660 There's no grid lines scale logarithmic or linear logarithmic base to base 10 or linear. 10:32.690 --> 10:39.650 These might be better shown if I'm using a specific metric value, so delete B and change that to see 10:39.650 --> 10:41.680 as the metric values. 10:41.720 --> 10:44.540 So I would go bring that down again. 10:44.540 --> 10:52.370 So logarithmic by two or by 10, I can see it like that and just linear. 10:52.610 --> 10:53.070 OK? 10:53.440 --> 10:56.930 Nexus Standard Options Unit. 10:57.590 --> 10:59.730 Here we can select Y. 10:59.730 --> 11:03.210 Our units are and it's just going to write the text square meters, for example. 11:03.260 --> 11:09.410 OK, so zero meter squared, one meter squared and the same on the axis there min is about showing the 11:09.410 --> 11:10.590 range of the graph. 11:10.610 --> 11:16.130 So let's say I want to show the minimum being 50 meters squared, so starts at fifty there and the max 11:16.130 --> 11:17.150 being sixty. 11:17.390 --> 11:21.530 So we're only showing just that part of the range there between 50 and 60. 11:22.130 --> 11:30.410 Order decimals at some decimals so that we can sit one point one two three four five twenty point three 11:30.410 --> 11:36.590 four five six seven and ninety point six, for example, if I show that again. 11:36.650 --> 11:42.410 So a series says twenty point three, despite the value being twenty point three four five six seven 11:42.410 --> 11:42.980 down there. 11:43.160 --> 11:48.320 So here the decimal option, I can say show me two decimal places. 11:48.540 --> 11:52.730 OK, so the A-series is now twenty point three five meters squared. 11:52.820 --> 11:55.490 OK, so next colour scheme classic pellet. 11:56.210 --> 11:58.370 That's the rainbow option, as I was showing before. 11:58.370 --> 12:04.430 So if I just switch the style back on, it's a graph style thing scheme the thickness of the rainbow. 12:04.820 --> 12:07.760 It's hard that go back down to a colour scheme. 12:07.760 --> 12:13.820 We have green, yellow, red, red, yellow, green, etc. There are several to choose from. 12:14.090 --> 12:15.170 Find one that you'd like. 12:15.440 --> 12:18.320 Moving on thresholds. 12:18.560 --> 12:22.850 OK, so thresholds show thresholds they are off at the moment. 12:22.850 --> 12:24.440 We can turn them on as lawns. 12:24.470 --> 12:30.050 OK, so we have one threshold at 80, then we can change that 50, for example, and they have a visual 12:30.050 --> 12:30.600 threshold. 12:30.600 --> 12:36.530 So they are just there to help you quickly see whether something is above or below a certain number. 12:36.560 --> 12:40.520 Here my value was a 50 could be a percentage, so it's 50 per cent. 12:40.520 --> 12:44.510 Now a percentage means thresholds relative to the mean and the max. 12:44.510 --> 12:50.420 So 50 percent between the middle of the max, which I could set above show thresholds as field region. 12:50.510 --> 12:57.230 OK, so green and red, I can change the colour of that yellow or blue like so as regions and lines 12:57.380 --> 13:00.530 next island in Bass, Spain back to green. 13:00.710 --> 13:01.180 Excellent. 13:01.190 --> 13:02.810 OK, so these are visual thresholds. 13:02.810 --> 13:09.830 They're not to be confused with alert thresholds, which will come onto later query value mappings. 13:09.860 --> 13:14.270 So value mappings are about what text to show when a value is at a certain point. 13:14.360 --> 13:15.920 So let's add a value mapping. 13:16.190 --> 13:16.940 Add new mapping. 13:16.940 --> 13:18.170 I'm gonna show range. 13:18.170 --> 13:23.170 For example, we could use projects or special values between 20 and 50. 13:23.180 --> 13:29.000 I'm going to show the text danger and I can set that colour to being a rate update. 13:29.420 --> 13:32.060 So the tooltip now shows red danger down here. 13:32.060 --> 13:36.860 It's just well, what it was before red danger, but a series being green? 13:36.860 --> 13:37.480 That's OK. 13:37.560 --> 13:39.050 This one here is also danger. 13:39.260 --> 13:44.060 OK, so this is an example of value mappings and there are different options. 13:44.150 --> 13:49.700 The value range rejects or special delete that update now. 13:49.730 --> 13:51.290 Data links at a link. 13:51.740 --> 13:53.510 These are a little more technical. 13:53.510 --> 14:00.950 When you click a data link, it will take some of the value that you have in your graph and send that 14:00.950 --> 14:02.870 to the URL that you're clicking. 14:02.870 --> 14:11.960 For example, title current value, for example Hasti TPS on slash slash often thought RSP code dot 14:11.960 --> 14:13.850 net slash $. 14:13.850 --> 14:18.550 That will bring up a bunch of options that you can send data to that URL. 14:18.560 --> 14:25.880 So for example, I want to send along the series name to the URL that I'm sending the user to. 14:25.910 --> 14:30.020 This is if you want to create dynamic content on another website, and you can use the query string 14:30.020 --> 14:35.750 to get values from so series name and just make that a little more like a proper query string. 14:35.760 --> 14:37.550 So s nine. 14:37.910 --> 14:39.230 And this is just an example. 14:39.320 --> 14:44.900 This is a lot more technical and more applicable for people who are programmers opening a new tab. 14:44.900 --> 14:47.120 So it's name a series name. 14:47.140 --> 14:52.190 So if I save that now, when you click on a value, it then gives you a link that you just. 14:52.390 --> 14:57.770 It so I called my current value down there could be called anything, so if I click that it will open 14:57.770 --> 15:04.850 in a new window, the URL will have this weary string s Eccles Series I as an extra parameter in the 15:04.850 --> 15:09.860 URL, and you can use those extra parameters for showing up important information that might be on a 15:09.860 --> 15:10.610 different system. 15:10.640 --> 15:13.310 So another example of that, if I edit that? 15:13.400 --> 15:19.070 Let's do another one saying value equals like that and show you straight away. 15:19.080 --> 15:22.930 Or I could have just pressed a dollar, but anyway, value equals. 15:22.940 --> 15:27.980 I'll send something else across, say, the whole time range that is selected. 15:27.980 --> 15:30.380 So value and that might be just better. 15:30.500 --> 15:32.890 Same time range save that. 15:32.900 --> 15:37.100 It's all about programming now, and whatever is important for the other system is what you would Typekit. 15:37.100 --> 15:38.630 So save that now. 15:38.630 --> 15:43.790 If I click one, there is my link, which I've named current value could have known that anything, 15:43.790 --> 15:50.780 and if I view the URL that it was sent to, it says time range equals from two and those times are actually 15:50.780 --> 15:57.840 the long equivalent of a time and that can be converted to a date time value at the end client. 15:57.860 --> 16:00.110 Anyway, I'm just showing you that these things exist. 16:00.890 --> 16:02.180 Okay, so that's dot links. 16:02.180 --> 16:03.990 Okay, so I don't need to delete that. 16:04.010 --> 16:04.790 OK, excellent. 16:04.790 --> 16:07.420 Now shining quite a lot about graphs already. 16:07.430 --> 16:11.600 You don't have to remember all of that or really understand exactly what all those things are doing. 16:11.630 --> 16:15.770 You can always come back to this video later or delve a little deeper into any particular subject. 16:15.780 --> 16:22.340 If you want a good place to see more examples of your photographs is the website that I showed you at 16:22.340 --> 16:26.390 the beginning, and this is actually play dot cofounder dot org. 16:26.420 --> 16:31.610 So this is a website built by the Gryphon developers that lets you test out all the different functionalities 16:31.610 --> 16:34.760 of Gravano without worrying about actually breaking anything. 16:34.820 --> 16:40.280 So, for example, if I want to know more about one of these graphs, this one, for example, thresholds 16:40.280 --> 16:46.970 here I can either press a an editor or I could have just press the added option there and understand 16:46.970 --> 16:50.990 how that graph is actually put together by looking at the different properties there. 16:50.990 --> 16:57.950 Legend graph styles access different overrides, which we'll talk about in the next video panel options 16:58.160 --> 17:01.120 and also understand a little more about its data source. 17:01.130 --> 17:04.740 These graphs are using a different data source noticed a DB. 17:04.760 --> 17:10.340 We haven't set up graphite, but you can see the play version has a lot of different data sources that 17:10.340 --> 17:12.360 you can understand a little bit more about as well. 17:12.380 --> 17:13.550 So I'll go right to the bottom. 17:13.580 --> 17:14.830 We'll get Test on DB as well. 17:14.840 --> 17:16.660 Random Walk, Refresh Refresh. 17:16.670 --> 17:18.320 Let's do a larger time. 17:18.320 --> 17:20.900 Okay, so there are some thresholds marked on that one. 17:20.930 --> 17:24.140 So if I get into thresholds, I can actually delete those. 17:24.140 --> 17:29.000 And don't worry if you break anything on this plague Ivana, the website, for example, I could say 17:29.000 --> 17:29.600 apply. 17:29.600 --> 17:32.810 And I've just ruined the thresholds graph for everybody. 17:32.810 --> 17:36.440 But actually, I haven't if I refresh this website. 17:37.390 --> 17:41.560 And look at the time series graphs again and scroll down. 17:43.400 --> 17:49.460 So Schultz is fixed up, so there's many things as you want, and there we go, if you go to dashboard's 17:49.460 --> 17:54.420 home, you can say there's a whole lot of other different types of graphs and options you might want 17:54.420 --> 17:54.590 on. 17:55.590 --> 18:00.210 Look at in more detail, so for example, I can press you on that one and learn all about that one. 18:00.300 --> 18:00.690 Excellent. 18:00.840 --> 18:04.860 So anyway, in the next video, we'll look at various kinds of overrides. 18:04.920 --> 18:08.250 It can filter just by override by pressing that option there. 18:08.370 --> 18:08.820 Excellent.
