I have a line graph chart which should display either a single or multiple series. It has three variables which can be set - these variables allow selection of single or multiple values.
When I run the report with single specific values set for all variables, the chart correctly displays a single series as expected. This works fine.
However when I set any of the variables to include multiple values, no data is displayed. The legend shows the correct multiple series as expected, and the Y axis scales to show the expected data range. However no lines appear on the chart.
If I run the stored procedure behind the report manually with any combination of variables, the correct data is returned. If I create a report which is exactly the same except that it displays the data in a table rather than a graph, it also returns the correct data. Therefore this seems to be working fine ... but still no lines appear!
This is for SSRS 2008 R2.
Does anyone have any ideas what this might be?
