Matplotlib’s “subplots” method lets us create subplots. Each subplot has its own place in the grid, which is based on the number of rows and columns in the grid and where the subplot is in that grid. This makes spotting or identifying trends, patterns, and relationships easier.Ī subplot is a grid of smaller plots that are part of a larger plot. We can compare and analyze multiple sets of data at the same time with the help of subplots. Subplots in Matplotlib allow multiple plots or charts to be displayed within a single figure. The current graph and plotting area are saved between function calls in matplotlib.pyplot, and the plotting functions are always applied to the active set of axes. Each pyplot function alters a figure in some manner, whether it is by adding a plotting area, plotting lines, adding labels, etc. The matplotlib.pyplot is a collection of command-style methods that allow matplotlib to function similarly to MATLAB. Tkinter, wxPython, Qt, and GTK GUI toolkits may include diagrams utilizing its object-oriented API. Matplotlib is a library that is mainly used for plotting graphs and plots for the Python programming language and NumPy, its extension for numerical mathematics. This article will discuss various methods for adjusting the position of the axis labels in Matplotlib. This can help users to easily understand the data that is being presented.įor creating labels and adjusting the labels we will use the Matplotlib library which is used for creating high-quality data visualizations. Note that the subplot index (the third argument) starts with 1 in the top left corner, counts up left to right, and then goes to the next row (similar to a phone dial).When we perform data visualization in Matplotlib using subplots or plots, it is important to label the axis correctly and adjust the position of the labels of the axis if required so that they do not overlap with other elements that are there in the plot. This can be useful if each set of axes has different characteristics (for instance, if some have 3D graphs and others do not) but starts to get tedious with a large number of subplots. This version requires that you set each up individually.

You can either set up six variables, one to access each axes, or you can set up a single 2D array that stores all six axes handles. Imagine you want to have two rows with three columns of subplots.

The add_subplot command will still create one at a time while the two different subplots() commands will now create 2D arrays of handles, meaning you will need to give two index values to access a plot. If you want more than one row and more than one column of subplots, you can also create them three different ways. This will become important when creating 3D plots.įigure window with two rows of three subplots and random numbers in the top middle subplot (after fig.tight_layout()) The only real difference between this version and the figure based one above is that this one will accept keyword arguments to be passed to the axes rather than to the figure. This is useful if you have an array of axes and you are planning to use all of them. It will return an array of axes handles (1D array if creating a single column or row, 2D array if there is more than one row and more than one column). The two main arguments for fig.subplots(nrows, ncols) will establish how many rows and columns you want to break the figure into.fig.subplots() needs you to create the figure handle first (probably with fig=plt.figure() and then you can use that figure variable to create an entire array of axes.You can also give the typical figure keyword arguments such as num=1, clear=True It will return a figure handle as well an array of axes handles (1D array if creating a single column or row, 2D array if there is more than one row and more than one column). The two main arguments for plt.subplots(nrows, ncols) will establish how many rows and columns you want to break the figure into.plt.subplots() allows you to create the figure and the axes handles at the same time.

This method can be especially useful if you want to build a figure with several non-overlapping subplots of different shapes - more on that below. The three main arguments for fig.add_subplot(nrows, ncols, index) will establish how many rows and columns you want to break the figure into and then which one of those subplots you want to work with.fig.add_subplot() needs you to create the figure handle first (probably with fig=plt.figure() and then you can use that figure variable to create one set of axes within an array of axes.There are three different ways to create subplots: 5 Multiple Rows and Columns of Subplots.4 Single Column of Subplots with Shared x Axis.
