When working with data, whether large or tiny, it is common to wish to compare things side by side or plot distinct traits or features independently. Finally, utilizing the GridSpec() method and the tight_layout() function, we can make our plots more adaptable, paving the road for the actual implementation of Subplots.Ī graphic is worth a thousand words, and thanks to Python's matplotlib package, creating a production-quality graphic takes significantly less than a thousand words of code.Various ways to produce plots (namely, plt.axes(), figure.add axis (), and plt.subplots ()), each of which is illustrated with a fleshed-out example.The intricacies of Subplots in Python by guiding you step by step through the basics to intermediary concepts, beginning with an overview of Subplots.In this article, we'll look at this function much more deeply. I hope you got a sense of what the subplots are. They are useful for comparison by aligning comparable properties and arranging columns side by side for easy display. Subplots allow numerous plots to be displayed on the same matplotlib figure. Subplots are important in data visualization for showing dense information. We're going to continue forward using the subplot2grid, applying it to our code that we've been slowly building up to this point, which we'll continue with in the next tutorial.Matplotlib, Python's most popular visualization package, supports numerous essential data visualization techniques for successful data analysis, including subplots. Obviously we have some overlapping issues here, which we can handle with the subplot adjusting.Īgain, try envisioning various configurations of subplots and make them happen with subplot2grid until you feel comfortable! This is how many rows and columns the axis will span. Next, we can optionally specify a rowspan and colspan. For ax1, this is 0,0, so it will start at the top. The next tuple is the starting point of the top left corner. We do (6,1), which means 6 tall and 1 wide. So, subplot2grid works by passing first a tuple, which is the grid shape. So, add_subplot doesn't give us the option to make a plot cover multiple positions. Next, let's cover the other method, which is subplot2grid. ![]() Try to think of some configurations that you think could be interesting, then try to create them with add_subplot until you feel comfortable. If you're having trouble visualizing this, see the video, as we also explain this works in paint, which should help if you're confused. Finally, 212 is a 2 tall, 1 wide, plot number 1. 222 is 2 tall, 2 wide, and plot number 2. So, a 221 means 2 tall, 2 wide, plot number 1. The way that this works is with 3 numbers, which are: height, width, plot number. Now, we're going to start with the add_subplot method of creating subplots: ax1 = fig.add_subplot(221) If you're following along linearly, then make sure to keep the old code on hand, or you can always revisit the previous tutorial for the code again.įirst, let's create our figure, use a style, create our figure, and then create a function that randomly creates example plots: import random For now, we'll start with a clean slate of code. ![]() There are two major ways to handle for subplots, which are used to create multiple charts on the same figure. In this Matplotlib tutorial, we're going to be discussion subplots.
