Re: Problems: date/time scale

My solution is as follows: I take the resultset and put the y-values in an 

array. While doing this I add the 'missing' y-values = 0 so that my

array contains the full year. Then I bind the array to Chart FX and let it

create its own x-values (like it is usual for a categorial axis). Afterwards

I set my desired labels along the x-axis to 'Jan', 'Feb' and so on.

This is somewhat complicated but in some case even better as in this case I

get only 12 values in my plot (and not 13 as in the case of the resultset with

the missing months) and these are at their correct position.

Not the best solution and not really satisfying but for the moment it works.

IMHO scaling and labelling should be further improved.
