Preconfiguration "Arrow of current value above the bar with graphic representation of value limits (PmiCanvas)"
The created complex item contains two PmiCanvas
subitems. The outer item 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 edgeof the item. 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 item 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 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:
|Measured value||Connection to measured value|
|Range from minimum||Start of range|
|Range to maximum||End of range|
|Color representation of value range|
