How to use nlnum in barchart

[leka]

I'm trying to create a report with simple vertical bars, showing bars with the data values on top of every bar, in nlnum format, with decending values.

When I import the data I select the nlnum format, so in the data importes showes the corret format.

First I tried to use the bar chart. The output is displayed as comma format instead of nlnum. There is an option for decending values, so thas ok. Is it possible to display the data as nlnum and on top of the bars?

Then I tried the wisard. Now the data values is display on top of every bar, but the format is comma instead of nlnum, and I can't find an option for sorting the bars in decending orders. Is there an option for sorting the bars in the wizard and formating the output format to nlnum?
