Column displayer
The column displayer shows the value of the connected object(s) by means of a single-colored column, which changes its height according to value changes.
Examples of column displayer displayed in the D2000 HI process:
 |  |
| Column displayer (one object connected) | Column displayer (3 objects connected) |
To create the column displayer
- In the Drawing toolbar, click the button Column displayer
. - Point the mouse cursor to the position of the first displayer corner and click.
- Point the mouse cursor to the position of the diagonal displayer corner and click.
The parameters for connecting a column displayer are being configured in the palette Connect object through the following tabs.
Objects
Object nr. 1 up to Object nr. 12
Each column displayer can display the values of as many as 12 objects. So the tab Objects contains input edit boxes allowing to define 12 objects. To define the objects to display in the displayer either enter their names or select them from a list opened after clicking the button placed right from the input box. The number of columns in the displayer depends on the number of connected objects.
Color for displaying given object is defined by clicking the button placed left from the input box.
For an object of Structured variable type, you must define column name (the parameter Column) and row number (the parameter Row). For an object of Value array you must define an item (the button L), whose value will be displayed.
Control
The parameters placed on the tab are identical to the parameters on the tab Control of the Connect object palette.
