I am facing a strange problem in designing a column chart. I have a page where i have two column charts. The data providr for both the charts is same. I have an xml with three categories of values, and each chart uses two of these with one of them being common and they are actually sorted based on one of those values. The problem here is that one chart shows proper values while the other (though shows proper values) it doesnt render it properly in the sense that the height of the columns and the value of that particular column are not consistent. What could be the issue????
