Preconfiguration "Histogram - Bar graph"
Creates the PmgCanvas
object configured as histogram - bar graph.
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 by using the pEvent.GetParentVar()
In the parent PmgCanvas
object, there are variables titles
Variable titles and colors are of the String type containing values separated by semicolon.
Variable textSize specifies the text size of graph legend.
Variable min and max specify the value scale range.
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:
- nTicks number of scale segments on Y-axis
- nSpaceY offset of X-axis from the bottom edge
These configurators can be set before the preconfiguration is created:
|Object name||Name (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, empty string, spaces and the first character must not be a number.
|Range from minimum (y)||Lower limit of Y-axis|
|Range to maximum (y)||Upper limit of Y-axis|
|Bar value ranges||Value ranges of graph bars separated by semicolon|
|Color||Colors in the HTML format (Working with colors description)|
|Values (y)||Base values on Y-axis separated by semicolon.|
|Data emulation in control variable binding||Emulated data will be generated in the control variable|
