Values between ticks in categorie diagram

With a macro I make a linediagram with categories. Calc sets the values automatically at the ticks of the x-axis. But I want to have the values (seen that this are categories) between the ticks. The solution shall be at com::sun::star::chart, but I can’t find it. Anyone knows it?
Thanks,
Dada

Nobody knows that. Change it manually to your liking and inspect the result.
