We have an application that creates and displays reports using SSRS 2.0 (it's a WPF desktop app, with a WindowsFormsHost region to display the report). Everything works great, until I get to a report that requires overlapping reports -- for example,
I have a bar chart with a control line that needs to be laid over the bar chart. To do this, I create two charts -- a bar chart to display my data, overlaid by a line chart where the value field is a constant, determined by parameter.
In the builder, this displays fine. I just had to set the "fill" for both the chart and the chart area (for the line chart) to "no color", and set all other grid lines & annotation to either "no color" or, where the option
is available, "none"; and then move it so that the Y axis for the control line lines up with the Y axis for the bar chart.
But when I actually run the application, the control line doesn't show at all. The documentation warns that in non-print mode it will display the two charts separately; but in print or non-print mode, it just doesn't display the line at all.
Has anyone else encountered this? Any suggestions of things I might be doing wrong? I've got about two weeks' experience using SSRS, so if there's a rookie mistake to be made, I've likely made it.
