By first editing the colours of category-fields and then renaming these categories, the colours are changing back to default colours. Although this is a logical way and behaviour, it would sometimes be helpful to preserve the colours. A button in the menu "Value order, colour" for optional preservation of the category colours would be helpful to save the edited colour-settings.
When you say "renaming", I presume you mean using "Edit value", either by right-clicking the value in the sidebar, or in the "Value order, colours and shapes" dialog for a text/category field.
If so, it would be possible to implement this idea. If, on the other hand, values are changing externally at source, it would not be possible, since Omniscope would not be able to automatically map old to new values.
Steve, thats right, I mean the edit value-function. It would be perfect to save the changed colours optionally (I understand it is sometimes helpful and the correct behaviour that the colours are changing automatically again).
is there any way of preserving category colours in 2.7. On refreshing our data the category colours go back to default colours even if the values (categories) have stayed the same.
