QLegend is a graphical object for displaying the legend of the chart. Legend state is updated by QChart, when
|
|
|
series have been changed. By default, legend is drawn by QChart, but user can set a new parent to legend and
|
|
|
handle the drawing manually.
|
|
|
User isn't supposed to create or delete legend objects, but can reference it via QChart class.

\brief Legend is part of Qt Chart QML API.
|
|
|
|
|
|
Legend is a graphical object, which displays legend of the chart. Legend state is updated by
|
|
|
ChartView, when series have been changed. Legend is used via ChartView class. For example:
|
|
|
\code
|
|
|
ChartView {
|
|
|
legend.visible: true
|
|
|
legend.alignment: Qt.AlignBottom
|
|
|
// Add a few series...
|
|
|
}
|
|
|
\endcode
|
|
|
|
|
|
\image examples_percentbarchart_legend.png
|
|
|
|
|
|
Please note that there is no QML API available for modifying legend markers, unlike in the Qt
|
|
|
API of Charts. The use case of modifying markers can be implemented for example by creating your
|
|
|
own custom legend. For an example on how to do this,
|
|
|
see \l {qmlcustomlegend}{Qml Custom Example} application.
