[Matplotlib-users] Adding grid to animation with blit

[Sandro T. <mat...@gm...>]

Hello,
I'm using blit to animate my plot, and I'd like to add a grid on it
but I failed at it.

What I do is:

1. prepare Figure, Axes, etc without plotting anything
2. save teh background with
     self.bg = self.canvas.copy_from_bbox(self.ax.bbox)

(on graph update)

3. restore background with
     self.canvas.restore_region(self.bg)
4. <line>.set_ydata(...)
5. self.ax.draw_artist(self.<line>)
6. self.canvas.blit(self.ax.bbox)

Now, I tried to place a "self.ax.grid(True)" in almost every possible
position, but never a grid came out :(

What is the right approach to solve it? Thanks in advance

Regards,
