Hi there

I am trying to create a 2D Stacked Column Flash chart, it is month based and for each month I have 3 Columns

So the query for the series returns a result set like so..

'Jan-11_Col1',10
'Jan-11_Col2',20
'Jan-11_Col3',30
'Feb-11_Col1',10
'Feb-11_Col2',20
'Feb-11_Col3',45
.
.
.
'Dec-11_Col1',20
'Dec-11_Col2',80
'Dec-11_Col3',100


I want to display a chart where the first column of the result set is my x-axis and the second column is my y-axis. I have have created the chart but I find I don't get a label for every columm on my x-axis, I only get one for every third column, and I can't see a way of doing it, can anybody tell me how?

thanks... Anil

ps I am using APEX 4
