Horizontal and vertical lines between subplots

Community matplotlib-users

Hi all,

I have created a figure with 4 subplots (2x2) and I want to separate them with a vertical and horizontal lines (see the green lines on my figure edited by Gimp) but I don't know if it's possible (I haven't find any example of that).

I am using Python 2.5.4 and matplotlib version 0.99.0

Thanks,
Maxime

Hi Maxime,

I hope my example works for you. Please note: I used plt.axes instead of
plt.subplot, although both generate an Axes instance, the latter doesn't
support overlapping axes.

Kind regards,
Matthias

Hi Matthias,

This is exactly what I wanted to do (excepted for the colors of the
lines which are quite horrible :slight_smile: )

Thanks a lot

Cheers,

Maxime

You may do this without creating an extra axes (ax0).
Try something like

ax4.plot([0.5, 0.5], [0, 1], color='lightgreen', lw=5,
         transform=gcf().transFigure, clip_on=False)

Hi Jae-Joon

This method is also great and it's working with plt.subplot:

from pylab import *
subplot(221)
subplot(222)
subplot(223)
subplot(224)
plot([0.5, 0.5], [0, 1], color='lightgreen', lw=5,transform=gcf().transFigure, clip_on=False)
plot([0, 1], [0.5, 0.5], color='lightgreen', lw=5,transform=gcf().transFigure, clip_on=False)

Thank you very much

Regards,
Maxime
