Data Analysis: Channel Value Pane

The Data Analysis Channel Value Pane can toggle plotter channels on/off and show channel specific measurements. It is an adjustable window pane located to the right of the plotter as shown in Figure 1. The entire pane can be toggled on and off using the "Show" main menu item.

Figure 1: The Channel Value Pane is located to the right of the plotter.

The Channel Value Pane lists all channels selected from the Tool Dialog. Click a channel checkbox to toggle the plotter display of that channel on and off.

The channel measurement columns (Table 1) can be enabled on the Graph Legend tab on the Plotter Options window. Open the window by selecting "Options" from the right click menu or the "Configurations" main menu.

Each column header in the channel list can be clicked to sort the column A-Z or Z-A. Also, the measurement columns can be rearranged by dragging and dropping their column headers to desired locations.
