The legend can be configured to display a variety of information on the variables, such
as:
• variable names
• aliases
• IDs
• descriptions
• current values
•
units of current values
•
the names of the tables from which the values of past and future times are retrieved.
In the case of line and area plots, the legend can display the (trend) values in the pointer's
location.
The legend can include text and separator rows:
• A text row presents variable data without a drawn graph.
• A separator row is a blank row.
The icons for text and separator rows are shown in Table 4.10-4.
You can change the following legend display settings:
• To display columns or item rows that do not fit in the screen area, scroll with the
scroll bar at the bottom or on the side.
• To fit more columns on the screen, reduce the width of each column.
•
Change the order of columns by dragging them.
This action does not apply to the icon column, since it
has a fixed position.
•
To hide a graph temporarily from the plot area, click the item type icon on the
variable's row. You can display the graph again by clicking the icon again.
•
Edit the variable of the plot in its column and/or in the history column.
You can select one or several variables for editing. If you select several variables, they
must be located next to each other in the same column of the legend rows.
To select one variable:
• Click the variable column on the row. The selected variable row is now highlighted
and the background color of the selected column is turned darker.
To select several variables:
• Click the outermost (lowest or topmost) variable column on the row you want to
include in the selection. The selected variable row is now highlighted and the
background color of the selected column is turned darker.
•
Press SHIFT and click the other outermost variable column of your selection. All
the selected rows are now highlighted.
You can now edit the variables in the column.
