Description
- The three projects attached all cause a crash for me when loading them.
- Create a function plot from file>new>new function plot double click on the graph, right click on the function (F1) and edit it click ok in the edit function window and then ok again in the plot details window and mantid will crash.

This stops crash when loading projects but doesn't fix the issue.

Trying to guard some pointers. Re #7117.
MantidPlot crashes when a MantidMatrix and a 3D graph are shown and you delete the underlying workspace in the dock widget. I am trying to find its cause.

- Status changed from accepted to verify
- Resolution set to fixed
To tester:
Please also test that projects containing 3D graphs can be saved, loaded and replaced with other projects.

Managed to find an issue:
- Create a qtiplot matrix
- fill it with values - I used Matrix->SetValue with sin(i/10)+sin(j/10) from 1-300 for both axes
- Plot the matrix as a 3D graph
- I also had a workspace and workspace based 3D graph (not sure if this is required)
- Save the project
- restart Mantid
- Load the project
- The qtiplot matrix 3D graph had lost it's colour and was all black. The Mantid based 3D graph was OK.

Corrected 3d plot style setting when openning project.

To tester:
The matrix must be large and the 3d plot must be "3D Polygons".
The problem was that the plot open from the project file becomes a "3D Wired Surface". The density of the wire lines is so high that they hide the coloured surface.

No crashes observed, though the crash which is similar to the one fixed here is described by ticket #7133
Save/load projects does not save/restore custom functions i.e. if you plot custom function, saved the project and then restored it the plot windows remains but function disappears. Its not a crash, so may be a issue for other ticket.
