Adjust Plot Bounds for Fixed Plots on Units Changes #86

Open eholum opened 8 years ago

eholum commented 8 years ago

Or should the values of the bounds not change when the units change? Or should the plot always reset on units changes?

I think the best way to update the plot ranges on a units change is to maintain the same "viewport", but with the axes in the new units. In other words, calculate the xmin, xmax, ymin, ymax, convert the mins/maxes to the new set of units, and set the plot ranges to the converted values.

So if you're zoomed-in on a region, then change the units, the plot should still be zoomed-in on the same data points. The units (and therefore the plot ranges) change, but the same data points are shown on the plot.
