Creates the
PmgCanvas object configured as layered bar graph.
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 values0,
values1, ... 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
The parent
Pmg object contains other
variables
- spaceX value defines the distance of Y-axis from the left border
- spaceY value defines the distance of X-axis from the bottom border
The preconfiguration is set for 4 values composing color layers of each bar. If you need to change the number of values (layers), then follow these steps:
- in the variable of the parent Pmg object change the number defined colors
- delete or create
variable valuesN in the embedded
Dynamic object
- on the "
Draw" tab of the embedded object make the change on the row marked by the comment
// other valuesThese 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. |
