Sometimes figures in color are not accepted, e.g. for publishing articles in journals. If this is the case, it is recommended to load the post-processing setup named BlackNWhite (do this from Window->Load Post-processing…). This setup will make sure that the background color is white and the curves are plotted in black. If several curves are plotted, instead of using different colors the curves are dashed or dotted. The defaults for this are set in Plot->Layout->Curve Styles and Colors….
If you are to change the curve style, see the How to change the curve style section. An example of a plot using this setup is shown below.
The plot can be saved from File->Export Plot…. If saved in the .tee-format, it can be opened again using the tee-files viewer. This can be useful if formatting adjustments are to be made later.
