Creates the
PmgCanvas object configured as - A single-line graph with a color fill specified by
y values.
This preconfiguration can be activated when
creating a new Pmg object.
This preconfiguration is included in the
"/ Chart, functions" group.
This object contains embedded
PmgCanvas object named "
Dynamic". The item has the
variable valY and
valX 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
Pmg object are accessible in the
onDraw event using the
pEvent.GetParentVar(sName).
In the
PmgCanvas object, there are
variables minX,
maxX,
minY,
maxY,
spaceX and
spaceY. These variables define the scale range in both
x and
y axes and also the offset of axes from left and bottom edge of the
Pmg object.
Additional configuration variables are located at the beginning of
context itself, or at the beginning of designer method. The following items can be set:
- colorScale color of ticks and scale descriptions
- nMajY number of main ticks on Y-axis
- nMinY number of minor ticks (between two main ticks) on Y-axis
- nDescPer specifies the quantity of displayed descriptors of main ticks (0 = no, 1 = every main, 2 = every second main)
- nMajX number of main ticks on X-axis
- nMinX number of minor ticks (between two main ticks) on X-axis
- colorArea background color of the graph rendering area
- colorGrid grid color
- nGridPer specifies quantity of displayed horizontal/vertical grid lines (0 = no, 1 = every main, 2 = every second main)
- nTextSize scale description text size
For embedded
Pmg object
- ctx.lineWidth = width of the rendered graph line
- ctx.strokeStyle = color of the rendered graph line
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 first character must not be a number. |
