DView stuck in auto-scale

[shorowit]

From Craig:

This version of DView seems to be stuck in ‘auto-scale.’

• Even though the program opens with ‘Autoscale’ unchecked, DView operates as though auto-scaling is on.

• If specific y-axis scale values are entered manually and ‘Autoscale’ is left unchecked , DView still operates as though auto-scaling is on.

For example -- in the attached file, first selecting ComEd2016 and then selecting ComEd2012, causes the y-axis scale max to increase from 3.4 to 4 – on either the upper or lower graph.

The guilty method is AutoscaleYAxisByPlot.

When adding a graph it's called from AddGraphAfterChannelSelection

The method itself forces update in each case in AutoscaleYAxis: https://github.com/NREL/wex/blob/develop/src/dview/dvtimeseriesctrl.cpp#L2569

The targeted behavior should be defined more clearly:

• If I add a graph, I want to retain the Min/Max Y Axis values I entered
• If I remove a graph, do I want it to calculate and update the Min/Max Y axis or retain my entered values?
