hello...i am having a line chart and column chart in one chart in a web template. The X-axis having one characteristics and the Y-axis is displaying the 2 key figures. One key figure is using column chart and another key figures is using line chart in one main chart. I have a navigation pane to drill down this chart. When I drill down this chart for one of the free characteristics, i have some problem on the legend. The legend does not displayed the correct information. Eg. supposely after drill down "horizontally" thru one of the free char, i should have 4 column chart in x-axis and 4 line chart in x-axis, but the legend display the wrong information which labelling the wrong chart type, in the end, i only have 3 column charts and 5 line chart. The legend displayed wrong information and the chart is wrong after i perform the drill down. does anyone know what's the problem?
