Description

Converting one or more scales from or to log changes the color bar even when the data being displayed hasn't changed. Sometimes the range displayed on the color bar far too narrow

"Rescale to show all" zooms out a long way when there is a negative data value in some log data. This is caused by calls to QwtPlot::setAxisAutoScale() but rescaling is good when this function isn't called and so it seems redundant. Ask Roman about removing a call to this function.

Sometimes the colour scale is nearly all white, happens for linear and log. Nick says that the colours shown in the scale on the right shouldn't change.

(In [4862]) Mantidplot was terminating when trying to plot colour plots with many nan values, so many nan values that the range of values in the data couldn't be assessed re #1265

This is about right clicking on a 2D plot of selecting Colour bar -> Log scale. Doing this works for me
