Preconfiguration "Arrow of current value above the bar with graphic representation of value limits (PmgCanvas)"
The created compound object contains two PmgCanvas
subobjects. The outer Pmg
object renders the scale and uses variables max
. Variables min
reprezent scale range. Variables barX
represent the dimension between the upper left edge of the bar and the upper left edge of the object. Variable colors
defines the color range of values (limits).
Additional parameters of scale rendering can be modified at the beginning of DrawScale method script.
The inner object Dynamic
has the variable val
. This variable controls the movement of the arrow along the scale. It can be binded to the measured value by data binding
Examples of limits and colors settings in the colors
Whole bar in a single color
(minimum - 20) = red, (20 - maximum) = gray
(minimum - 20) = red, (20 - 30) = yellow, (30 - 70) = gray, (70 - 80) = yellow, (80 - maximum) = red
These configurators can be set before the preconfiguration is created:
| Object name||Name (identifier) of the Pmg object. It is used to obtain the Pmg object by the PmgObject.Items method. |
This configurator sets the initial value of the property Name.
This is a system name, so it must contain only alphanumeric and must not contain any diacritics, empty string, spaces and the first character must not be a number.
|Measured value||Connection to measured value|
|Range from minimum||Start of range|
|Range to maximum||End of range|
|Color representation of value range|
