Visualization settings: axes limits, units, ...

This issue was reported by Riccardo Scandroglio.

When I open a SMET file that has been produced with Snowpack, Snopviz reads the visualization settings (axes' limits, units, colors, ...) from the SMET file.

Anyway, in my Snopviz, under Datei/Einstellungen, I already have my personal settings and I would like Snopwiz to use those settings and not the ones in the SMET file. Right now every time I have to open the SMET file and delete the ""plot"" lines of the HEADING, to be able to use my favourite view.

Expected result: Snopviz should use my settings (the ones that are normally in Snopviz) and not the ones from the SMET-file.

Suggestions:

• you could add the possibility to choose which setting to use in the menu Datei.
• would be more practical to be able to change the axes' limimts directly from the interface (maybe also synchronized).
