This blog is part of my series Making Data Tell a Story With SSRS Properties.

Property: Tooltip

The purpose of this property is to show a specific value on a series in a chart when the user hovers over the data point.

To access the property, select a chart series and go to Tooltip.

Example: I have a line chart that shows sales by category by year. I want the user to be able to see the exact value as a tooltip.

I go to the Design tab, click on the series to select it, and choose Tooltip and add my expression. I am summing the value, and formatting it as currency.

When I run the report and hover over a point, the value of that point shows in a yellow tooltip box.
