The Item Details Area
Overview
The region immediately below the plot within the Plot Window is known as the Item Details Area. This area is used to display details relating to each item that is assigned to a pen within the active plot.
Should an item value rise above or drop below the scale set for it, an Off Scale Indicator will appear next to the details for that item.
Note: For Radar plots the Item Details Area is distributed around the circumference of the radar plot at the end of each radial rather than being located at the bottom of the plot.
Tip: By double clicking on the required item it is possible to use the Item Details area to launch the Plot Properties dialog with the focus set on the chosen item.
Choosing the fields to display
By default, the item details area will show two rows of data per pen. These will show the Display name and the Value for each pens. The User can choose how many rows of data should be displayed for each pen.
Other options are:
-
Item Name
-
Description.
-
Data Location
-
Scan Frequency
-

-

For more information see the Plot Properties View tab
Tip: Should sufficient items be mapped to pens such that the item details cannot fit on the plot, then a left and right hand spin button will appear such that the user can 'scroll' through the items.

Group Scales
|
Apply a Group Scale usability function to the pens within the current plot. This will add pens to one or more new scale group depending on whether they match the criteria for the chosen operation.
Valid options are:
-
PV's and SP's - the logic works through all the pens in the plot, creating a scale group for each PV & SP pair found using the item name to seed the group name.
-
X-axis Pens - create a single group scale and assign all X-axis pens to it.
-
Y-axis Pens - create a single group scale and assign all Y-axis pens to it.
-
OP's - if any OP's are found they are all added to a scale group called "All OP's".
-
All Pens - all the pens in the plot are added to a scale group called "All Pens".
Note: The X and Y axis options are only applicable to X/Y Graph Styles.
