For most graphics, the colour and appearance can be freely selected. To do this, double-click on the text next to the coloured symbol for the graph in the tree view.

In addition to the colour, pen styles can also be selected. Depending on the graph, however, these may look different in the display than in the selection box in this dialogue box. The pen thickness can also be adjusted. You can also specify whether the individual values calculated by CGRAPH for the display of a function should be connected with lines.

The example shows the approximate appearance that can be expected later in the graphical display.

Note: Some graphics also allow you to change colours and appearance within a list of default values.
