Data in charts can be exported to Excel (or other WINDOWS packages).
To export the data that makes up the graph ensure the graph is displayed on screen, if you chart is not being displayed Simul8 does not collect any data for it. Then access the Chart properties through the Design tab Charts button. Select the chart of interest and click the Export Data button.
The data that makes up the graph can now be pasted into another application such as Excel where you can perform detailed analysis.
