One possible way to get a graph is to use TRANSUM.
- Enable Transum (Analyze -> Enable Protocols -> Transum RTE Data
- Add port 3306 to Transum (Preferences -> Protocols -> TRANSUM -> Output RTE data for these TCP service ports)
- Draw Graph (Statistics -> I/O Graph -> Add new graph: display filter: transom.art, Y-Axis: AVG or MAX(Y Filed), Y Field: transum.art)
