Working with Graphs

Inserting Multiple Logger Files
You can insert more than one Logger file into a single Graph file. This enables
you to easily compare data, and is especially useful for before-and-after studies
or to check interactions of data collected from different loggers.
To insert additional Logger files into a Graph file, follow the instructions in In-
serting Logger Files on page 44 for each Logger file you want to insert.

To scroll the graph to the right:
1. Do one of the following:
• Select Format>Scroll Forward.

Pinpointing Graph Values and Times
To pin-point exact values and times on the currently-active graph:
1. Do one of the following:
• Select Format>Position Cursor.
• Press F7.
• Right-click the graph, and then select Position Cursor.
• Click the Position cursor icon on the toolbar ( ).
2. Position the cursor line along the X axis using the mouse or the arrow keys.
The values at the bottom left portion of the window indicate the exact date
and time where the cursor line is positioned as well as the exact values that
correspond to that point.
