To verify the installation, you can start a Python interpreter by typing python or python3 in your command line interface and then run the following command: python import matplotlib print(matplotlib.__version__) If matplotlib is installed correctly, this will print out the version number of m...
Clear a Plot in Matplotlib with clf() In order to clear the currently drawn Graph/Chart, we can use theclf()function (Which I believe stands for “clear figure“). An example of how it may be used it as follows: 1 2 3 4 5 6 7 importmatplotlib.pyplot as plt f1=plt.figure() pl...
