This makes things so much easier especially when you draw plots from tables and with that feature one doesn't have to look at that table any more to look for a coordinate to add a pin or label. > I hope this helps. You have no idea. Many thanks for that hint! But I heard from a reliable source that there will be an at least even alternative in the next release ;) Best regards, Stefan
