Preconfiguration "Polar chart"

Creates the PmgCanvas object configured as polar chart.
 
This preconfiguration can be activated when creating a new Pmg object and is included in the group: " / Chart, functions".
 
This object contains embedded PmgCanvas object named Dynamic. The item has the variable values and arcus of the String type containing values separated by semicolon. It is posible to connect it to the measured value of the same data structure by data binding. The variables of the parent object are accessible in the onDraw event by using the pEvent.GetParentVar().
 
In order to draw the chart correctly the angles (range 0 - 360) are stored in arcus variable in ascending order and the corresponding values are in the values variable.
 
Additional configuration variables are located at the beginning of context itself, or at the beginning of designer's methods. The following items can be set:
nScaleCount - The number of circles (values) of the scale
nFontSize - Font size of the scale descriptors
colorScale - scale circle(s) color
colorText - scale descriptor color
posAngle0 - Chart orientation when angle is 0°
sColorLine - chart line color
sColorFill - chart area color
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 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.
