Hi allI've come across a bit of an issue where I need to display different data depending on the field in the report.For the majority of the data in the tablix, I need to show the data corresponding to the month selected by the user.However, I also want to show a sparkline graph showing the year-to-date position (for the last 12 rolling months).I've got most of it working apart from the sparkline (which is coming from a different dataset) and I just can't get that to work.I thought about adding an item to the original dataset to show the rolling 12 months in it but that gives me duplicated rows and makes a mess of the original dataset.It appears to be possible by changing the dataset name just for the sparklines but I can't see how to get it working (and Google just shows what people have tried without success).Has anyone got this to work and, if so, can they let me have a step-by-step guide please?
