Hi Maginor

The problem with zoom is that the grid spacing would have to be adequate with different zoom levels and scroll. From example:
- If X goes from 0 to 10, spacing could be every 2 (2, 4, 6, 8 )
- If X goes from 321 to 501, spacing could be every 40 (361, 401, 441, 481)... or adjusted to more rounded values, every 50, like (350, 400, 450, 500)

Maybe as an intermediate solution, we could add something similar to that you propose, although, instead of returning a Vector<double>&, I would propose to add a callback returning Vector<double>&, with the values of the grid positions adequate to that level of zoom.

What do you think?


Best regards
IƱaki
