Graph issue

[Paloncho]

Hello All,
I'm having some issues with graphics too.
Graphic grid is ok, vertical label, title, etc.... But the curious thing is that it is not graphing inside the grid. I mean, there's no statistics inside the grid (it's a connections graph). Everything else is ok, I see all the labels and numbers in grid, but it isn't showing anything inside the graph.
I've compared this one with others graphics that are working ok and there are no differences... so, I don't know what's going on in this one.
Did anyone have this same issue?

I'll wait for your answer.

Regards.
