Re: Highlighting the axes of coordinates

Changing the properties of the individual grid line can be tricky.
The easier way in my opinion is to draw another line with thinker linewidth.

ax=subplot(111)
ax.grid()

from matplotlib.transforms import blended_transform_factory

# for x=0
trans = blended_transform_factory(ax.transData, ax.transAxes)
ax.plot([0,0], [0,1], "-",
        transform=trans,
        color="red", linewidth=2,
        zorder=5)

# for y=0
trans = blended_transform_factory(ax.transAxes, ax.transData)
ax.plot([0,1], [0,0], "-",
        transform=trans,
        color="blue", linewidth=2,
        zorder=5)
