Preconfiguration "Bar graph with default x-axis"
Creates the
PmgCanvas object configured as 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,
colors,
textSize,
min,
axis and
max.
Variable titles and colors are of the String type containing values separated by semicolon.
Variable textSize variable specifies the text size of graph legend.
Variable min and max specify the value scale range.
Variable axis specifies the starting value of bars rendering.
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 |
|---|
| Value of default X-axis | The value between min and max used as the default value for rendering the graph bars |
|---|
| Range to maximum (y) | Upper limit of Y-axis |
|---|
| Bar names | The names of graph bars separated by semicolon |
|---|
| Color | Colors in the HTML format (Working with colors description) separated by semicolon. |
|---|
| 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 |
