Without the logarithmic scale the data that we plotted would show a curve with an exponential rise.

Log scale matplotlib x axis.

They are just forwarded to axes set xscale and axes set yscale to use different properties on the x axis and the y axis use e. Using the log scale with set xscale or set yscale function only allows positive values by letting us how to manage negative values while. Log 10 x y means 10 raised to power y equals x i e 10 y x.
