+    \brief The QLineSeries class is used for making line charts.
+
+    \mainclass
+
+    A line chart is used to show information as a series of data points
+    connected by straight lines.
+
+    \image examples_linechart.png
+
+    Creating basic line chart is simple:
+    \code
+    QLineSeries* series = new QLineSeries();
+    series->append(0, 6);
+    series->append(2, 4);
+    ...
+    chart->addSeries(series);
