I am having a Combo Chart with a Multi box for selecting Products, on selection graph values will change accordingly. When there is no selection, I am able to see vaoues on Bars of Chart i.e values are large, however when I select any Product from Multibox, expression values are small so unable to see values on Bars. Is there any way where small Expression values are visible on selection i.e dynamically scale can be changed for big and small values.
Actualy by default the graph scale is dynamic, unless you did change it to the static scale. Check your Axes properties. Another possibility that you have another expression on the same graph, which returns a much larger values. In this case, use different position (same Axes properties) for the bars, so there will be different scales for the left(bottom) and right(top).
