Using the Graph Analysis Tools to Graph Data
k 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 7 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.
• To select an analysis mode and draw a graph
1. On the E-CON3 main menu (page ε-1), press 5(GRAPH).
• This displays the Graph Mode screen.
2. Press 3(MODE), and then select the analysis mode you want from the menu that
appears.
To do this:
Perform this menu
