Adjusting gridlines on a 3D Matplotlib figure

Question

I\'m getting ready for a presentation and I have some example figures of 3D matplotlib figures. However, the gridlines are too light to see on the projected images.

Answer 1

If you don't mind having all the lines thicker then you could adjust the default rc settings.

Given a graph such as:

We can add:

import matplotlib as mpl
mpl.rcParams['lines.linewidth'] = 2

To increase the default line width of all lines, giving a result of:

Alternatively, if you feel this looks ugly, you could use:

ax.w_xaxis.gridlines.set_lw(3.0)
ax.w_yaxis.gridlines.set_lw(3.0)
ax.w_zaxis.gridlines.set_lw(3.0)

to adjust the line width of each axis to 3.0, producing:

In order to update the colour, so the grid-lines really pop, you could add:

ax.w_xaxis._axinfo.update({'grid' : {'color': (0, 0, 0, 1)}})
ax.w_yaxis._axinfo.update({'grid' : {'color': (0, 0, 0, 1)}})
ax.w_zaxis._axinfo.update({'grid' : {'color': (0, 0, 0, 1)}})

Which produces:

The methods are pretty hacky, but as far as I am aware there is no simpler way of achieving these results!! Hope this helps; let me know if you require any further assistance!
