Refs #9098 Ranges now show correct colours.
Refs #9098 Only allow minimum of 0.001 for bin width.
Refs #9098 Make range selector info only.

It's difficult to select the correct binning by dragging the range selector.
This approach is also consistent with the way binning is selected on the Fury interface.
