Plot refresh behavior

[Mathieu Doucet]

A few users have complained that the x-scale of plots updates/rescales when the plotted workspace updates. Users would like their choice of axis options (log vs linear, or range in x) stick even after a workspace change.

Moved at end of release 2.1

The live data work has made getting this fixed more important.

Re #5107. Don't auto-rescale axes if limits manually set.

If a user sets limits on a particular axis, these will stay fixed until told otherwise (via e.g. 'Rescale to show all). Previously, if the backing workspace updated the graph would rescale back to the full range of the data, which was particularly annoying for live data viewing. They would also rescale if errors were added

• this is also fixed. Changeset: 242307193a0ac7ccab1d63bb868cd7191ddcb218

Re #5107. Keep fixed axes fixed when drag-dropping from a workspace

onto an existing MantidCurve.

Re #5107. Remove unused method/member.

This was added at some point after the fork from QtiPlot, but never used. We use the underlying QwtPlot axis attributes.

Re #5107. Allow fixing of axes on curves from 'plot bins' commands.

The deleted lines caused them to flip back to autoscaling every time the workspace changed.

Re #5107. Ensure that autoscaling=no preference is respected.

Previously, even if the autoscaling option was unchecked in the 2d plot preferences, several plot types would have it enabled.

This should be sorted now. In particular, manually-set axis limits should not be lost when (a) a workspace updates, (b) a new curve is inserted or (c) errors are added to a curve.

Axes are considered fixed if they are manually set (via the dialog or python) and are independent (e.g. the abscissa can be fixed while the ordinate still automatically rescales). Setting fixed axes back to autoscaling is available from python commands, the 'Rescale to show all' right-click option or the 'Best fit' toolbar option. The 'Autoscaling' option in the 2D plot preferences should be respected (though I'm not quite sure why you'd want it turned off. Zooming should also work as before.

Colour fill plots behave slightly differently - the colormap does not rescale automatically

Seems to work according to the description. Works both via GUI and from python.
