calculated y axis MIN and MAX value are wrong

[derkasek]

Hello everybody!

I have a problem with the scale of the y axis of a graph.
The MIN and MAX value are set to "calculated" and the calculated values are just wrong (at least not optimal).

Example (for one day):
actual MIN value: 395.823 M (illion)
actual MAX value: 398.675 M (illion)

the calculated values are:
MIN: 360 M
MAX: 420 M

The result is a flat line, which is obviously not desired.

Any hints?
