Scaling of the Y-axis

[hreintke]

I have a temperature + humidity sensor.
When showing the graphs the "day graph y-axis values" are set that the full y-axis is used.

But for month and especially year, the values are very high low so I get very "flat" graphs.
Year actual values are between -6 and + 34, scale is from -24 to +72.

Is there a way to "rescale" or manually set axis values ?
