Fix Contour Labels Location

Problem:

When exporting a picture, the location of the contour labels changes:

Left: the on-screen plot, Right: the resulting image export

Solution:

By default the image is rendered off-screen and implies a re-draw of the plot. There are two possible solutions:

1) Prevent the re-positioning of the labels when a redraw occurs:

In the Contour Details dialog, in the Labels tab, toggle Generate automatic labels (with each withdraw) off.

Deactivating the automatic generation of labels at each redraw.

2) Prevent the redrawing by using the on-screen plot when exporting an image:

In the Options>Performance menu, on the Rendering tab, set the Image Export Options to Fast (use on-screen image).

Setting the image export to match the on-screen plot.
