Charting table grouped data in SSRS line chart?

Question

Hi,

I have an SSRS table with data that is grouped. I am trying to chart that grouped data, however I'm finding it difficult to connect the table grouping paradigm to the chart grouping.

Essentially I have two nested columns, a time and value and I would like to chart those at the group level.

Here's what it looks like:

Group 2

---Group 1

-----time|value

I'm having trouble figuring out how to tell the chart to use the time|value pairs inside my group. Time on X axis and Value on Y.

Any advice appreciated.

Thanks in advance!!
