![]() We then saw how to use the fontsize and prop parameters to change the font size of a Matplotlib legend. We first saw what a legend is in Matplotlib, and some examples to show its basic usage and parameters. It can be used to describe the elements that maker up a graph. Operating system: Matplotlib version: Matplotlib backend ( print (matplotlib. In this article, we talked about the legend function in Matplotlib. Here's the output: matplotlib legend size using prop parameter Summary subplots () to create a new figure, specify figsize: f, axs plt. Here's how to use it: import matplotlib.pyplot as plt 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. How To Change Legend Font Size in Matplotlib Using the prop ParameterĪnother way of changing the font size of a legend is by using the legend function's prop parameter. You'd also notice the legend was placed at the upper left corner of the graph using the loc parameter. We assigned a font size of 20 to the fontsize parameter to get the legend size in the image above: fontsize="20". ![]() Here's what the legend would look like: matplotlib legend size using fontsize parameter Plt.legend(, fontsize="20", loc ="upper left") However, no matter what I try, I cannot seem to get the x and y labels to increase in font size to 20. Here's another code example with the fontsize parameter included: import matplotlib.pyplot as 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. We can also add figure-level x- and y-labels using FigureBase.supxlabel and FigureBase.supylabel. ![]() Plt.show() matplotlib graph with default legend font size 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. Here's what the default legend font size looks like: import matplotlib.pyplot as plt You can change the font size of a Matplotlib legend by specifying a font size value for the fontsize parameter. How To Change Legend Font Size in Matplotlib Using the fontsize Parameter You can change the position of the legend using the following values of the loc parameter: This makes it easier for anyone viewing the graph to know that the blue line denotes age while the orange line denotes number in the graph. Matplotlib tightlayout () tightlayout (). In the graph above, we've used the legend function to describe each line in the plot. Mattlotlib tightlayout (), subplotsadjust () subplottool () Matplotlib. Plt.show() two line graph with different legend descriptions Python Matplotlib Matplotlib Suraj Joshi 2023130 2020612 Matplotlib Matplotlib Subplot tightlayout () plt.subplotsadjust () plt. Here's an example: import matplotlib.pyplot as plt With the legend function, you can assign different descriptions to each line of a graph. A description of "Data" was assigned to the legend, and was placed in the upper right corner of the graph using the upper right value of the loc parameter. ylabel, position or list of label, positions, default None Allows plotting of one column versus another. ![]() xlabel or position, default None Only used if data is a DataFrame. In the graph above, we described the plot using a legend. 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. Parameters dataSeries or DataFrame The object for which the method is called. Plt.show() matplotlib graph with a legend ![]() You'll then learn how to change the font size of a Matplotlib legend using:Ī legend is a Matplotlib function used to describe elements that make up a graph.Ĭonsider the graph below: import matplotlib.pyplot as plt In this article, you'll learn what a legend is in Matplotlib, and how to use some of its parameters to make your plots more relatable. 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.You can modify different properties of a plot - color, size, label, title and so on - when working with Matplotlib. Modify Default Values of rcParams Dictionary Import numpy as np import matplotlib.pyplot as plt x =np. ![]()
