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, min, barX, barY and colors. Variables min and max reprezent scale range. Variables barX and barY 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 the "DrawScale" method script.

The inner Dynamic object 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 variable:
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 nameName (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 Name property.

The maximum name length is 30 characters. 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.
