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 60 for each Logger file you want to insert.
Removing Channels from the Graph
After viewing a Graph that contains one or more Logger files -- or a single Log-
ger file with multiple channels -- you may want to remove a channel and its as-
sociated graph lines for a cleaner view.
To remove a channel from the active graph:
1. From the Channel Information table, highlight the channel to remove and
do one of the following:
• From the menu, select Edit>Remove Channel...
• Right-click the channel in the Channel Information table, and select
Remove Channel...
2. A confirmation window opens. Click Yes to confirm.
The channel and its associated graph line are removed from the active Graph.

the left. Each time you scroll, the graph view shifts by one graph division.

1. Do one of the following:
• Select Format>Scroll Backward.
• Press A LT +Left Arrow.
• Click the Scroll Backward icon on the toolbar ( ).
To scroll the graph to the right:
