Re: [Matplotlib-users] "zig-zag" to represent suppressed 0 on axis?

[ChaoYue <cha...@gm...>]

Hi Kevin,

I don't check the link you provided very carefully. So I guess you already
find a solution.
otherwise I have done something similar before and have made a bit general
function to do
the job, which I think might be helpful for you.

You can check the following three functions at
https://github.com/ChaoYue/pylsce/blob/master/g.py

Calc_Newaxes_Fraction
Axes_Replace_Split_Axes
Axes_Set_Breakaxis

a working example is below:

>>> fig,axs = plt.subplots(nrows=2)
>>> bottom_ax, top_ax =
g.Axes_Replace_Split_Axes(fig,axs[0],split_fraction=[0.36,0.04,0.6],direction='v')
>>> g.Axes_Set_Breakaxis(bottom_ax, top_ax, 0.01,0.03,'v')
>>> left_ax, right_ax =
g.Axes_Replace_Split_Axes(fig,axs[1],split_fraction=[0.38,0.02,0.6],direction='h')
>>> g.Axes_Set_Breakaxis(left_ax, right_ax, 0.03,0.02,'h')

the figure is as attached.

cheers,

chao
