Matplotlib pyplot semilogy make a plot with log scaling on the y axis.
Log scale matplotlib.
The process to plot logarithmic axes is extremely similar to regular plotting except for one line of code which is specifying the type of axes as log.
If we have to set both axes in the logarithmic scale we use loglog function.
We use set xscale or set yscale functions to set the scalings of x axis and y axis respectively.
Each of the axes scales are set seperately using set xscale and set yscale methods which accept one parameter with the value log in this case.
Additionally custom scales may be registered using matplotlib scale register scale these scales can then also be used here.
