Currently when you create a graph you have the ability to fix the Y min and Y max on a standard graph.
There are circumstances where I would like to display multiple item values from related data where the range of these data are very different, for example, receive level on a wireless link (range -30 to -90) and the transmit power on the same link (range +10 to +30).
If I use a the scale on a single axis the data would be very compressed and not very readable.
Using the above ranges of the two datasets, I would like to be able to set a fixed data range for the left axis and a fixed data range for the right access.
Left Axis - (min = -90, max = -30) - showing receive level
Right Axis - (min = +10, max = +30) - showing transmit power.
Having these two different scales for the left and right axis on the graph would make the data much more readable.
