Destroys the Fl_Chart widget and all of its data.
The add method adds the value and optionally
label and color to the chart.
The autosize method controls whether or not the chart will
automatically adjust the bounds of the chart. The first form returns a
boolean value that is non-zero if auto-sizing is enabled and zero is
auto-sizing is disabled.
The second form of autosize sets the auto-sizing property
to onoff.
The bounds method gets or sets the lower and upper bounds of
the chart values to a and b respectively.

pos. Position 0 is the first data value.

value, label, and color. Position 0 is the
first data value.

- FL_LINE_CHART
