chartsEnginge and Histogramm

[Till Bandi]

I would like to use charsEngine to represent a Histogram. Does anyone  
have an idea how to do that.

When I use barsgrouped chart I get a chart I could use, but the data  
is sorted which should not be the case. If for instance I have the  
data 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 then the bars are  
1,10,11,12,13,14,15,2,3... that means that a alphabetical sort takes  
place and I did not find a way to stop that.
