4.2.5.1.7 Setting the Background Color
Black is the default background color for graphic displays and models. This may not be the ideal choice in
all circumstances; for example, you may wish to use the background color of a graphic to identify the plant
area to which the graphic applies.
The BG tab of the Settings window is used to change the background color of the graphic being config-
ured. To change the background color of the graphic in the active child window, click on the button repre-
senting the desired color from the palette. The background of the graphic will change to that color. (For
more detailed information on use of the color palette, see the sub-section
Section 4.2.5.1.3, Fill Color
Selection .)
The background color is assigned during configuration. If the user decides to change the background
color, the graphic must be reconfigured and installed again; that is, the background color cannot be
changed while the graphic is on display in an Operator Window. Note that when configuring dynamic sub-
models, background color is configurable as the erase color, the color used to replace portions of the draw-
ings when they are removed from the submodel. When a color is assigned to a submodel via the BG tab
on the Settings window, the following message will be displayed in the status bar:
erase color = n
where n is the number of the color selected from the color palette. When an instance of a submodel is
made on a graphic, the instance assumes the background color of the graphic. When portions of the sub-
model are erased, the background color assigned during submodel configuration is displayed in place of
the original color used. A good example of this is a dynamic submodel such as a tank when used in a
larger graphic display. As the level decreases in the tank, the color representing the ingredients is replaced
by the background color selected for the tank, instead of the background color of the graphic.
4.2.5.1.8 Setting the Grid Attributes
The grid used in the Working View area of a child window aids in the construction of models. Use the grid
as you would a piece of graph paper, as a guide in designing objects. The grid size, line style (lines, dots,
hidden) and grid color can all be configured using the Grid tab on the Settings window.
Configurable attributes for the grid are style, size, and color. The grid style is selected from a drop-down
combo box. The choices are Lines, Dots and Hidden.
Grid size choices are 1x1, 2x2 and NxN. The numbers represent Working View units; the default Working
View is 100 units wide by 75 units high, regardless of the size of the window or the display screen. The 1x1
option will cause the grid to reflect this and divide the Working View into 100 units by 75 units. The 2x2
option provides a grid with a line drawn every two units. To make the selection, click on either the descrip-
tion or the associated indicator box.
The choice NxN allows you to specify the size of the units which compose the grid. When this option is
selected, the text entry box associated with it becomes available. Enter a value from 0.2 to 10 in this text
entry box. The grid size will be adjusted accordingly. If a value outside these limits is entered, the grid will
be resized using the closest available size. For example, if 500 is entered, the 10x10 grid size will be used.
To change the color of the grid in the active child window, choose a button from the Grid Color palette. The
grid lines will change to the selected color. Two hundred fifty-six colors are available, numbered 0 through
255. These are contained on eight pages of 32 colors each, which are displayed one page at a time. To
✎ Note
This feature is for use only on graphic displays, and does not allow
the user to change the background color of other display types
(such as Point, Group, Trend and Summary displays, and so on).
The background colors of these display types were chosen to
provide the best contrast with other colors used in these displays.
