Preconfiguration "Arrow of current value above the bar with graphic representation of value limits (PmgCanvas)"
This preconfiguration can be activated when
creating a new Pmg object and is included in the group:
"/ Bar (PmgBar)".
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 distance between the left upper corner of the bar and the left upper corner 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:
Example:
Whole bar in a single color
#c0c0c0
(minimum - 20) = red, (20 - maximum) = gray
#ff0000;20;#c0c0c0
(minimum - 20) = red, (20 - 30) = yellow, (30 - 70) = gray, (70 - 80) = yellow, (80 - maximum) = red
#ff0000;20;#ffff00;30;#c0c0c0;70;#ffff00;80;#ff0000
These configurators can be set before the preconfiguration is created:
| The name of created object | Name (identifier) of the Pmg object. It is used for obtaining 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 (i.e. national dependent characters), empty string, spaces and the first character must not be a number. |
