The subplot() function takes three arguments that describes the layout of the figure.. Numpy and Matplotlib. It sets both X-axis and Y-axis to have the same range. The aspect ratio of a matplotlib plot refers to the aspect of the axis scaling, i.e. The layout is organized in rows and columns, which are represented by the first The data is arranged over a meshgrid and then plot_surface is called for plotting a surface plot. If we pass "square" as an argument to matplotlib.pyplot.axis (), it creates a square plot where the ranges for both axes occupy are equal to the length in plot. So, instead of using traditional circular markers, we can also use square markers and it also looks good. The range of axes in this solution are selected automatically. Import the matplotlib.pyplot library into your project. LinkedIn We can generate a square plot using matplotlib.axes.Axes.set_aspect () method. plt.legend () method is used to add a legend to the plot and we pass the bbox_to_anchor parameter to specify legend position outside of the plot. Linux For this, we need some basic concepts of two popular modules in the field of plotting figure i.e. Then we used the concept of gcawhich return the current axis instances on the current figure. Then we created a numpy array and stored it in a variable named as pts, then we passed this numpy array in Polygon module. import numpy as np import matplotlib.pyplot as plt from scipy.stats import chi2 #x-axis ranges from 0 to 20 with .001 steps x = np.arange(0, 20, 0.001) #plot Chi-square distribution with 4 degrees of freedom plt.plot(x, chi2.pdf(x, df=4)) You can also modify the color and the width of the line in the graph: The explicit axis limits set by the user are not respected. The function takes parameters for specifying points in the diagram.
