Preconfiguration "Meter"

Creates the PmgCanvas object configured as meter.

This preconfiguration can be activated when creating a new Pmg object and is included in the group: "/ Meter".

This object contains embedded PmgCanvas object named "Dynamic". It controls the movement of the meter pointer by using the variable named "val". It is possible to connect it to the measured value by data binding.

In the parent PmgCanvas object there are variables min and max defining the value range of the meter. The space value specifies the distance of the scale from the object margin. The posAxis value specifies the distance of the scale from the top edge. Additional configuaration variables are located in the context itself, in the section beginning with the USER VALUES comment.

Additional configuration variables are located at the beginning of context itself, or at the beginning of designer's method. The following items can be set:
- colorScale - scale and description color
- fontSize - description text size
- majTicks - number of main ticks of the scale
- minTicks - number of minor ticks between main segments
- nDescPer - the quantity of main segment descriptors (0 = no, 1 = each main, 2 = each second)
- bgColor - the background color of the meter
- color1 and color2 - the values define the background colors of the meter
- borderWidth - width of the meter border
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 (i.e. national dependent chars), empty string, spaces and the first character must not be a number.
