Hi,

I 'd like to zoom on the y axis with the Wheel tool but keeping the graph "glued" to the line y=0..
Is there a simple way to do that ?

Thanks

Lionel

Hi Lionel,

I am not entirely sure from your description, but it sounds like you just want to have panning enabled in one dimension, but not another? If so, constraining the pan tool is described here:

Thanks,

Bryan

Hi Bryan,

thanks for your fast answer,
my problem is not about allowing one dimension..
I didn't explained well.. simple problem but not so easy to explain... My problem is to zoom on the edge (with the wheel tool) but not around the point on which is stopped the mouse but around the origin.
ie : If I "edge-zoom" on y axis I would like the 0 to be always visible ..
Wish I was clearer
