Hi, I have been unable to figure out how to plot time series with lines and others with dots programmatically. (I know how to edit a plot manually with the plot editor, but I would like to have an an automatic solution with Hansl scripting for a simulation project.) Here is what I can do with Gretl, using the attached time-series data. example.gdt. By using the GUI with View->Graph specified vars->Time-series plot ... and selecting all variables I get the following graph: [IMAGE] Using the plot editor I can change the appearance of orig_slope to [IMAGE] Can this be done by scripting, and if so, how?
