Settings are generally at three different levels:
- Application settings such as visible decimal places,
- Project Options such as unit preferences, and
- Scenario Options that you may want to change for different scenarios.
We also have a page that describes how users can improve the performance of scenario runs using a number of different settings under Improving Performance.
Source graphs can be customised both individually and globally, from the Recording Manager or by choosing Tools » User Chart Settings.... Refer to Customising chart views for further detail.
