\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.
