Preconfiguration "Wind direction chart (compass-card)"
Creates the
PmgCanvas object configured as wind direction 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 of the
String type containing values separated by semicolon. It is possible 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 using the
pEvent.GetParentVar().
In order to draw the chart correctly the average values of wind strenght in corresponding times are stored in
values variable. These are 8 or 16 values separated by semicolon where the first value is north and further directions follow clockwise.
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:
nScaleCount - The number of scale rasters
nFontSize - Descriptor font size
colorScale - Scale circle(s) color
colorText - Descriptor color
sColorLine - Chart line color
sColorFill - Chart area color
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. |
