It can be used in Python scripts, the Python and IPython shell, web application servers, and various graphical user interfaces, etc. The keyword argument marker of the scatter () function is used to set the shape of the markers. 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. The third argument represents the index of the current plot. Demonstrating matplotlib.pyplot.polar() Function - Python Pool MatPlotLib with Python. The aspect ratio of a matplotlib plot refers to the aspect of the axis scaling, i.e. 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: Matplotlib Surface Plot - Tutorial for Beginners - MLK - Machine Aptitude que. Here, we created another object named as plt.rectangle() which takes mainly 3 arguments, first one indicates the position of left-bottom corner of rectangle, and the next two arguments indicates the width and height of the rectangle. For this, we need some basic concepts of two popular modules in the field of plotting figure i.e. So, if we want a figure with 2 rows an 1 column (meaning that the two plots will be displayed on top of each other instead of side-by-side), We can generate a square plot using matplotlib.axes.Axes.set_aspect () method. The fc attribute is used to denote the face color of the rectangle and the ec attribute denotes the edge color of the rectangle. rcParams["scatter.marker"] (default: 'o') for Axes.scatter).
