Summary0013876: 2d plot - log Y axis is broken
DescriptionThere is a major bug in the log of the axes on 2d plots. It replicates as follows:

* 3.98.1, Linux, local server.
* Load can.exo. All variables on. Apply.
* Plot over line filter. Apply. Turn all variables on, all off. Then, only turn on Global Node Id.
* On the 2d viewport, Edit View Options. Left Axis/ Layout. Turn on "Use Logarithmic Scale When Available". The Y axis no longer has a scale.

This needs to be fixed ASAP.

There were several issues with the vtkAxis class as well as charts that relied on the vtkAxis for scaling information:

1. Log-scaling could be requested but there was no way for a chart to know whether it would be enabled by the axis or not (without duplicating code from the axis class).

2. Some classes need access to axis ranges as specified (ParaView UI) while others need to know the range of values that the transformed plot coordinates span (vtkPlot*). The chart API in VTK now provides both.

3. Some plots (vtkPlotBar) ignored log-scaling altogether.

4. The logic to compute tick labels when log scaling was requested, feasible (min*max > 0), but not reasonable (less than 1 order of magnitude between min and max) was broken.

It should be possible to verify the fix by retrying the steps above to demonstrate the problem, as well as the use cases in bug 13877 and 13899.
