[mrtg] scaling the graphs - the curve is at the very buttom of the graph

[Leonard Krivopaltsev]

Hi everybody

I am measuring IO writes. I set my max to 40M (41943040), which maximum throughput.
On the vertical scale, MRTG draw the scale up to 24M, but my actual curve max is ~500K/sec - so the graph sits at the buttom. Why mrtg did not scale it correctly? My max peak for that value has been 1M/sec.

How can i force it to rescale to something more meaningful?
thank you

here is my config
