Axis Properties - second axis
For the second axis, the properties can be set as shown above. Additionally available scaling options are:
Manual scaling: enter fixed values for the minimum and the maximum of this axis - enter 0 for both to
disable this feature.
Auto-scale on: enables the auto-scaling feature - the axis will be scaled so that all selected data are
visible.
Auto-scale limits: these settings are used to obtain a nice looking graph in two special situations:

datasets with very low noise:
In the auto-scaling mode, the graph looks as if there are extreme variations, but the
range is very small due to the auto-scaling. In this case, it is better to use the option:
lower limit: lower than
and
upper limit: higher than
This leads to a minimum span in the graph.

datasets with outliners:
In this case, it is difficult to analyze the data because the auto-scaling generates a
high span value. To prevent this, please use:
lower limit: higher than for outliners with low values
and
upper limit: lower than for outliners with high values
This leads to an optimized span in the graph.
