Preconfiguration "Bar graph with default x-axis"
Creates the complex graphic item PmiCanvas
configured as bar graph.

and is included in the group: " / Trend, functions, chart"
This graphic item contains embedded PmiCanvas
item named Dynamic
. The item has the variable values
of the string
type containing semicolon-separated values. The binding
can be used to connect it to the measured value of the same data structure. The variables of the parent item are accessible in onDraw

- nTicks number of scale segments in the y
- nSpaceY offset of x axis from the bottom edge
These configurators can be set before the preconfiguration is created:
|Range from minimum (y)||Low limit of the y axis|
|Value of default x-axis||The value between min and max used as the default value for rendering the graph bars|
