Selecting an Analysis Mode and Drawing a Graph
This section contains a detailed procedure that covers all steps from selecting an analysis
mode to drawing a graph.
Note
• Step 4 through step 6 are not essential and may be skipped, if you want. Skipping any
step automatically applies the initial default values for its settings.
• If you skip step 2, the default analysis mode is the one whose name is displayed in the
top line of the Graph Mode screen.
