Static Max problem

[#1]

Hi folks,

My problem has to do with Static max on a bar chart. It seems like the chart looks at the max of the Static max values and actually not on the Static max value on the individual expressions.

This screenshot shows my chart Stacked. This is what the customer wants except that extra light grey space for 22 for Sep 2013.
They of course want the Sep 2013 bar chart to end at 21 because that month is a working day shorter than Sep 2014.

     This is the exact same chart but Grouped. See how Sep 2013 now ends at 21 as it should.
 
  To be able to accompish this I have an expression for Static max which results in the total number of days for the month. 22 for Sep 2014 and 21 for Sep 2013. It seems that the Static Max function only takes the highest value into consideration when displaying the chart.

Anyone seen this and has a solution?

Thanks
