+/*!
+  \brief A class for drawing markers
+
+  A marker can be a horizontal line, a vertical line,
+  a symbol, a label or any combination of them, which can
+  be drawn around a center point inside a bounding rectangle.
+
+  The setSymbol() member assigns a symbol to the marker.
+  The symbol is drawn at the specified point.
+
+  With setLabel(), a label can be assigned to the marker.
+  The setLabelAlignment() member specifies where the label is
+  drawn. All the Align*-constants in Qt::AlignmentFlags (see Qt documentation)
+  are valid. The interpretation of the alignment depends on the marker's
+  line style. The alignment refers to the center point of
+  the marker, which means, for example, that the label would be printed
+  left above the center point if the alignment was set to
+  Qt::AlignLeft | Qt::AlignTop.
+
+  \note QwtPlotTextLabel is intended to align a text label
+        according to the geometry of canvas
+        ( unrelated to plot coordinates )
