\class Fl_Chart
\brief Fl_Chart displays simple charts.
It is provided for Forms compatibility.
\image html charts.png
\image latex charts.png "Fl_Chart" width=10cm
\todo Refactor Fl_Chart::type() information.
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.
