Round values in Y-Axis in statistics diagram

[xyCommander]

Hi.
I would like to suggest an option to round the values for the y-axis in statistics diagram. When only enabling the middled values and setting the axis to automatic range, there is some strange behaviour which compresses the diagram (see picture). Its because HA calculates the values on way to many numbers after the comma. So giving users the option to round and choose the length of the values after the comma (maybe 2-4 digits) would be nice. I'm pretty sure, nobody needs 13 or 14 digits here ;)
Thank you

Addition: In Germany we use point and comma in the exact opposite way. So in local mathematics I mean the calculation after the comma, for HA and the picture below I mean the calculation after the point...
