bug in moving points

[sct]

If you make a grid that is a short range on the Y axis like (0.53 to 0.43) you will notice a bug when moving a point. It causes a script error and halts. The left image is a chart with many point on the left( same values ) and one point on the right. I grabbed the green point and moved it in the second image, producing the error.

Hi,

Excuse us for the delay here.
I could reproduce the hang&crash so I've added it to the wish list to be revised for next releases (TF77016692).
