Analysing a Graph

The tool bar carries a button that puts the graph into analysis mode. With it pressed, can be used to bring in another set of graph lines for comparison. Pressing it opens a dialog similar to Goto, as shown.

Analysis can keep adding lines indefinitely, and works alongside the other graph movement commands. A graph with comparison data mixed in looks like this.

When you have finished analysing, press again to leave analysis mode, or press to return the graph to the present time.
