Detailed Description
An item to render a bar chart.
This chart renders
Usage example

Definition at line 24 of file BarChart.h.
Member Enumeration Documentation
enum BarChart::WidthMode |
Helper enum to provide an easy way to set barWidth to auto.
Definition at line 46 of file BarChart.h.
Property Documentation
|
readwrite |
The width of individual bars in the chart.
If set to WidthMode::AutoWidth (also the default), the width will be calculated automatically based on total chart width and item count.
Definition at line 40 of file BarChart.h.
|
readwrite |
The spacing between bars for each value source.
Note that spacing between each X axis value is determined automatically based on barWidth, spacing and total chart width. The default is 0.
