Hi,
What is the easiest way to plot a histogram with a logarithmic x-axis? The
Axes.hist() method takes a log=True/False argument, but this applies only to
the y axis.
Is the only solution to plot a histogram of np.log10(array) and to change
the tick formatter to a Log formatter, or is there a more straightforward
way?
Thanks,
Tom

Hi Tom,
I'm not sure I understood correctly, but maybe the attached example goes
towards a solution ...
best regards Matthias

Hi Matthias,
This is exactly what I need - I did not know about the xscale function.
Thanks!
