WEBVTT 1 00:00:00.000 --> 00:00:01.540 Hi guys and welcome back. 2 00:00:01.540 --> 00:00:02.760 In this video, we're going to learn 3 00:00:02.760 --> 00:00:05.750 how to export one figure with multiple sets 4 00:00:05.750 --> 00:00:07.710 of axes inside it. 5 00:00:07.710 --> 00:00:09.030 There's nothing magical about it. 6 00:00:09.030 --> 00:00:11.060 As you can see, the code is pretty short 7 00:00:11.060 --> 00:00:12.690 but let's get to it. 8 00:00:12.690 --> 00:00:14.530 Here we've got a figure. 9 00:00:14.530 --> 00:00:16.590 Inside of it, we've got two subplots 10 00:00:16.590 --> 00:00:21.590 that are in two columns and these are the IDs one and two, 11 00:00:21.620 --> 00:00:22.700 and then each one of them, 12 00:00:22.700 --> 00:00:24.100 we're plotting a line chart. 13 00:00:24.100 --> 00:00:25.490 Nothing too fancy here. 14 00:00:25.490 --> 00:00:27.580 I just wanted to show you how you can do this. 15 00:00:27.580 --> 00:00:30.060 At the end, we're doing savefig as before 16 00:00:30.060 --> 00:00:32.110 and all that's gonna happen when we run this 17 00:00:32.110 --> 00:00:33.840 is we're gonna create our image 18 00:00:33.840 --> 00:00:37.140 and it has the two elements here. 19 00:00:37.140 --> 00:00:40.540 Remember that if we do plt.show instead, 20 00:00:40.540 --> 00:00:43.183 so we'll do plt.show here, and we run this, 21 00:00:44.200 --> 00:00:45.810 we've got our configuration 22 00:00:45.810 --> 00:00:50.510 and here we can adjust the spacing between plots like that. 23 00:00:50.510 --> 00:00:55.000 So the width space or wspace goes from zero to one. 24 00:00:55.000 --> 00:00:57.270 Zero means there are completely joined together. 25 00:00:57.270 --> 00:01:01.700 One means that the space between two graphs 26 00:01:01.700 --> 00:01:05.340 is equal to the average width of an x-axis. 27 00:01:05.340 --> 00:01:08.580 So here you can see this, this and this 28 00:01:08.580 --> 00:01:09.917 are all the ame width. 29 00:01:09.917 --> 00:01:12.580 .5 though means that the width between two graphs 30 00:01:12.580 --> 00:01:16.090 is equal to 1/2 of the average width of an x-axis. 31 00:01:16.090 --> 00:01:18.960 And so it is pretty handy to separate graphs more 32 00:01:18.960 --> 00:01:21.080 or less appropriately. 33 00:01:21.080 --> 00:01:22.670 Hspace is the same but of course, 34 00:01:22.670 --> 00:01:25.010 it separates in rows rather than columns 35 00:01:25.010 --> 00:01:26.270 and we only have one row here, 36 00:01:26.270 --> 00:01:28.110 so it doesn't take effect. 37 00:01:28.110 --> 00:01:30.490 However, this can be handy when you want 38 00:01:30.490 --> 00:01:31.690 to produce an image. 39 00:01:31.690 --> 00:01:36.240 You can adjust the spacing between plots for better export. 40 00:01:36.240 --> 00:01:38.180 So let's try to do that without plt.show. 41 00:01:38.180 --> 00:01:39.806 I'll bring back figure.savefig 42 00:01:39.806 --> 00:01:42.087 and now we can do here figure.subplots_adjust wspace 43 00:01:43.870 --> 00:01:45.710 equals 0.5 let's say. 44 00:01:45.710 --> 00:01:47.150 We can run this 45 00:01:47.150 --> 00:01:48.850 and what we get now is that the graphs 46 00:01:48.850 --> 00:01:50.183 are a bit more separated. 47 00:01:51.060 --> 00:01:53.170 Not that we've got some pretty larger borders 48 00:01:53.170 --> 00:01:54.350 around the graphs 49 00:01:54.350 --> 00:01:55.830 and we can get rid of them using 50 00:01:55.830 --> 00:01:57.520 the tight bounding box method. 51 00:01:57.520 --> 00:02:01.110 So we can do bbox_inches equal tight 52 00:02:01.110 --> 00:02:03.770 and that is going to get rid of some of those borders 53 00:02:03.770 --> 00:02:05.110 so we can open this again 54 00:02:05.110 --> 00:02:06.900 and now they're a bit closer to the edge. 55 00:02:06.900 --> 00:02:09.130 Do note, of course, if you add the titles 56 00:02:09.130 --> 00:02:10.940 or axis labels and stuff like that, 57 00:02:10.940 --> 00:02:13.870 there will still be room for those as well if you need them. 58 00:02:13.870 --> 00:02:17.500 So just to recap, the savefig call changes the size 59 00:02:17.500 --> 00:02:18.333 of the figure. 60 00:02:18.333 --> 00:02:20.450 You can set it to constrain the plot inside it 61 00:02:20.450 --> 00:02:23.000 with bbox_inches equal tight 62 00:02:23.000 --> 00:02:25.470 and you can also add padding if you want. 63 00:02:25.470 --> 00:02:28.970 This subplots_ adjust method here changes each 64 00:02:28.970 --> 00:02:30.320 of the plot's settings 65 00:02:30.320 --> 00:02:33.840 and here we've used it to distribute the plot horizontally 66 00:02:33.840 --> 00:02:35.060 a bit better. 67 00:02:35.060 --> 00:02:37.990 But the other settings in here also take effect 68 00:02:37.990 --> 00:02:40.448 as we've seen in this video and in the last. 69 00:02:40.448 --> 00:02:42.280 Thank you, guys for joining me in this video. 70 00:02:42.280 --> 00:02:43.520 I hope you've learned something 71 00:02:43.520 --> 00:02:45.170 and I'll see you in the next one.
