\property QXYSeries::pointLabelsFormat
|
|
|
The \a format used for showing labels with series points.
|
|
|
|
|
|
QXYSeries supports the following format tags:
|
|
|
\table
|
|
|
\row
|
|
|
\li @xPoint \li The x value of the data point
|
|
|
\row
|
|
|
\li @yPoint \li The y value of the data point
|
|
|
\endtable
|
|
|
|
|
|
For example, the following usage of the format tags would produce labels that have the data
|
|
|
point (x, y) shown inside brackets separated by a comma:
|
|
|
\code
|
|
|
series->setPointLabelsFormat("(@xPoint, @yPoint)");
|
|
|
\endcode
|
|
|
|
|
|
By default, the labels format is set to '@xPoint, @yPoint'. The labels are shown on the plot
|
|
|
area, labels on the edge of the plot area are cut. If the points are close to each other the
|
|
|
labels may overlap.
