PyDM TimePlot AutoRangeX is always False

[teddyrendahl]

I ran into this issue with the following use case:

I have a PV I want to plot over a long period of time (~12 hours). In this specific case, it is a temperature that we want to make sure doesn't wander too far. However, since the X axis is always fixed my plot is useless for the first half hour because the timeSpan is huge and my buffer is small at first.

I even tried to set the autoRangeX at runtime by right clicking the plot, but every time the PV updates it resets the X axis to the full timeSpan. What I want is the plot to slowly expand as the buffer fills.
