When a histogram is edited update( ) is called on the histogram, which calls update( ) on its vectors. However, the curve which is created at the same time as the histogram is left untouched, so its maximum and minimum values are unchanged. This applies to equations and psds also.

Reloading from the toolbar fixes this as all the curves are updated.

One possible solution would be to have the histogram, equation, or psd hold a reference to the curve. The curve could then be updated when necessary.
