How to display a toal number above the stacked bar chart

Hi,
I have a question about stacked bar chart.

I could display each member value of a staked bar chart according to the follow sample:
06_bar_chart\05_stacked_chart.html

The problem is how to get a total value which sums the value of each bar in a stacked bar and then to put the sum on top of the stacked bar chart.

As you see the example above , each department sale result for each year is displayed. However, annual sale amount was missing in the sample. This missing point is exactly what im looking for now.
please let me know how to put the total value on top of the stacked bar.

Thank you for your cooperation in advance.
best wishes,
tomas

Hi,

currently it is impossible to show a label on the top of a stacked bar. We’ll add this feature into 3.0 version. That you is going to be released soon.
