\qmlclass ChartView DeclarativeChart
ChartView element is the parent that is responsible for showing different chart series types.
The following QML shows how to create a simple chart with one pie series:

Theme defines the visual appearance of the chart, including for example colors, fonts, line
widths and chart background.

Deprecated; use margins instead.
The minimum margins allowed between the outer bounds and the plotArea of the ChartView. Margins
area of ChartView is used for drawing title, axes and legend. Please note that setting the
properties of minimumMargins may be bigger than the defined value, depending on other ChartView

\qmlsignal ChartView::onPlotAreaChanged(rect plotArea)
The plot area of the chart has changed. This may happen for example, if you modify minimumMargins
or if you resize the chart, or if you modify font size related properties of the legend or chart
title.
