![]() ![]() However, no matter what I try, I cannot seem to get the x and y labels to increase in font size to 20. Set titles for the figure and the subplot respectively fig.suptitle(bold figure. Python3 import matplotlib.pyplot as plt import numpy as np fig, ax plt. 18 I have made a phase plot of a bistable stable, with the nulclines on the main graph and have added a subplot with the trajectories overlaying it. The user has a great deal of control over text properties (font size. We can also add figure-level x- and y-labels using FigureBase.supxlabel and FigureBase.supylabel. subplots () to create a new figure, specify figsize: f, axs plt. Each axes can have a title (or actually three - one each with loc 'left', 'center', and 'right'), but is sometimes desirable to give a whole figure (or SubFigure) an overall title, using FigureBase.suptitle. We are creating random data by using random.randint to plot our graph and then setting a single title for all the subplots. setfigheight on the object returned by plt.subplots (), or set both with f.setsizeinches (w, h): f.setfigheight (15) f.setfigwidth (15) Alternatively, when using. You might also take a look at plt.figlegend(). Example 1: In this example, we will import the required library and create a 22 plot. Have a look at the matplotlib legend guide. Novemby Zach How to Add Title to Subplots in Matplotlib (With Examples) You can use the following basic syntax to add a title to a subplot in Matplotlib: ax 0, 1.settitle('Subplot Title') The following examples shows how to use this syntax in practice. # Shrink current axis's height by 10% on the bottomĪx.set_position([box.x0, box.y0 + box.height * 0.1,Īx.legend(loc='upper center', bbox_to_anchor=(0.5, -0.05), The enumerate (axs.flatten ()) function is used to iterate over each subplot (or ‘axes’), and the ax.hist (data i) function is used to plot a histogram of the i-th dataset on the i-th subplot. # Put a legend to the right of the current axisĪx.legend(loc='center left', bbox_to_anchor=(1, 0.5))Īnd in a similar manner, shrink the plot vertically, and put a horizontal legend at the bottom: import matplotlib.pyplot as plt In this code, plt.subplots (2, 2, figsize (10, 10)) creates a 2x2 grid of subplots. Line, = ax.plot(x, i * x, label='$y = %ix$'%i)Īx.legend(loc='upper center', bbox_to_anchor=(0.5, 1.05),Īlternatively, shrink the current plot's width, and put the legend entirely outside the axis of the figure (note: if you use tight_layout(), then leave out ax.set_position(): import matplotlib.pyplot as pltĪx.set_position() Similarly, make the legend more horizontal and/or put it at the top of the figure (I'm also turning on rounded corners and a simple drop shadow): import matplotlib.pyplot as plt If we do the same thing, but use the bbox_to_anchor keyword argument we can shift the legend slightly outside the axes boundaries: import matplotlib.pyplot as plt So, let's start with a generic example: import matplotlib.pyplot as plt ![]() By using Figsize, you can change both of these values. For example, to plot data on the first subplot, we can use ax 0, 0. We can access each subplot using the ax object returned by subplots (). Next, we can plot the data on each subplot using the plot () function from matplotlib. This parameter is governed under the rcParams attribute of the figure. We also specify the size of the figure to be 8 inches wide and 6 inches tall. This size can be changed by using the Figsize method of the respective figure. ![]() To add to what and already said, you can use the bbox_to_anchor keyword argument to place the legend partially outside the axes and/or decrease the font size.īefore you consider decreasing the font size (which can make things awfully hard to read), try playing around with placing the legend in different places: The size and font of title and axes in Matplotlib can be set by adjusting fontsize parameter, using setsize () method, and changing values of rcParams dictionary. In Matplotlib all the diagrams are created at a default size of 6.4 x 4.8 inches. We can change default rc settings stored in a global dictionary-like variable called matplotlib.rcParams to set the fontsize of labels and title of plots in Matplotlib.Ī complete list of the rcParams keys can be retrieved via () function Keys Description axes.labelsize Fontsize of the x and y labels axes.titlesize Fontsize of the axes title figure.titlesize Size of the figure title (Figure.suptitle()) xtick.labelsize Fontsize of the tick labels ytick.labelsize Fontsize of the tick labels legend.fontsize Fontsize for legends (plt.legend(), fig.legend()) legend.title_fontsize Fontsize for legend titles, None sets to the same as the default axes.There are a number of ways to do what you want. How to Add Title to Subplots in Matplotlib D deepanshurustagi Read Discuss Courses Practice In this article, we will see how to add a title to subplots in Matplotlib Let’s discuss some concepts : Matplotlib : Matplotlib is an amazing visualization library in Python for 2D plots of arrays. Modify Default Values of rcParams Dictionary Import numpy as np import matplotlib.pyplot as plt x =np. ![]()
