We can change the scale of the axes of the histogram in python by specifying the value True to the argument log in the () function.

We can specify the value ‘mask’ or ‘clip’ to the arguments nonposx and nonposy. Matplotlib handles the negative values for the log scaled axis of the graph by specifying the arguments nonposx and nonposy for the x-axis and y-axis respectively.
