+
+  The type of an Fl_Chart object can be set using type(uchar t) to:
+  \li \c FL_BAR_CHART: Each sample value is drawn as a vertical bar.
+  \li \c FL_FILLED_CHART: The chart is filled from the bottom of the graph
+         to the sample values.
+  \li \c FL_HORBAR_CHART: Each sample value is drawn as a horizontal bar.
+  \li \c FL_LINE_CHART: The chart is drawn as a polyline with vertices at
+         each sample value.
+  \li \c FL_PIE_CHART: A pie chart is drawn with each sample value being
+         drawn as a proportionate slice in the circle.
+  \li \c FL_SPECIALPIE_CHART: Like \c FL_PIE_CHART, but the first slice is
+         separated from the pie.
+  \li \c FL_SPIKE_CHART: Each sample value is drawn as a vertical line.
