Select and delete series manually within RasWCT diagram widgets

[Jelmer Oosthoek]

I would like to request the following functionality for RasWCT. Is it possible to add the ability to manually select one or more series in the diagram widget with the mouse and press DEL to remove? Or use CTRL-click to select more, or draw a rectangle to select series? Or another way to do a manual delete? In short, the common select object methods used in various software. Maybe through a special ‘select’ button which enables this?
