Report Viewer: Interacting with reports
There are a number of ways to interact with reports in the Report Viewer. Your available options depend on how the report was designed and the type of content in it.
Tip: If your environment has Action Events, you may have access to more interactive features than are listed in this section.
Drilling into data
Some reports allow you to drill down into cells or charts to see some additional data related to the field you selected. If a cell or chart has a drilldown, you can click on one of the values to drill down into the related data.
Drilldowns are actually other reports that you can interact with or even export to a file. Drilldowns may even have drilldowns of their own!

Chart features
Charts have a number of interactive features depending on the type of chart. For example, line charts and bar charts allow you to hide series, multi-axis charts allow you to turn axes on or off, and pie charts allow you to rotate the chart and pull out slices. Charts can also show some additional information if you hover over a point or series.
