Changing the colour, line style or elements in an existing plot via Python can be done by modifying the Data Series object of a plot. The Data Series object contains the information for all shown…
The contents of result objects (ElmRes) are exported via the Result Export command (ComRes). This command offers various options: Export type (e.g. csv, COMTRADE, txt, databases) Option to export all…
