Property Documentation

backgroundColor : color

The background color of bars in the chart.

By default this is Qt::transparent. If set to something non-transparent, the chart will render backgrounds for the bars. These backgrounds will have the same width as the bars but stretch the full height.


barWidth : real

The width of individual bars in the chart.

If set to BarChart.AutoWidth (also the default), the width will be calculated automatically based on total chart width and item count.


orientation : enumeration

The orientation of bars in the chart.

By default this is BarChart.VerticalOrientation.

ConstantDescription
BarChart.HorizontalOrientationBars are oriented horizontally, with low values left and high values right.
BarChart.VerticalOrientationBars are oriented vertically, with low values at the bottom and high values at the top.

radius : real

The radius of the ends of bars in the chart in pixels.

By default this is 0, which means no rounding will be done.


spacing : real

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.
