GGU-TIME-GRAPH: "Manually" menu item

Generally, the automatically generated triangle mesh is very high quality. However, there are cases in which you might want to generate a different interpolation between individual points. Using this menu item, you can create a triangle mesh completely by hand or rework an existing mesh. A message box provides information on the procedure:

To define a triangle mesh (interpolation mesh) the data points are first displayed in their correct locations.

If no points are visible, got to the "Page size + margins/Auto-resize" menu item or use the [F9] function key.

Then click three data points with the left mouse button; these then represent an interpolation triangle. Repeat this process until all the required data points are integrated into the triangle mesh. By pressing the right mouse button you can reset a triangle.

The triangles may not overlap as this will almost always lead to nonsensical contours. You can have this condition tested by the program by going to the "Contours/Test" menu item.

If you want to delete an existing triangle, click the points of the triangle once more. By pressing the right mouse button you can reset a triangle.
