21.2.2 XYPlot Types

The following types are available:

FL_NORMAL_XYPLOT

A solid line is drawn through the data points.

FL_SQUARE_XYPLOT

Data drawn as a solid line plus squares at data points.

FL_CIRCLE_XYPLOT

Data drawn as a solid line plus circles at data points.

FL_FILL_XYPLOT

Data drawn as a solid line with the area under the curve filled. Only data points are drawn with. per default, stars.

FL_LINEPOINTS_XYPLOT

Data drawn as a solid line plus, per default, stars at data point.

FL_DASHED_XYPLOT

Data drawn as a dashed line.

FL_DOTTED_XYPLOT

Data drawn as a dotted line.

FL_DOTDASHED_XYPLOT

Data drawn as a dash-dot-dash line.

FL_IMPULSE_XYPLOT

Data drawn by vertical lines.

FL_ACTIVE_XYPLOT

Data drawn as a solid line plus squares at data points, accepting manipulations.

FL_EMPTY_XYPLOT

Only the axes are drawn.

All xyplots per default display the curve auto-scaled to fit the plotting area. Although there is no limitation on the actual data, a non-monotonic increasing (or decreasing) x-axis might be plotted incorrectly.

XYPlots of type FL_POINTS_XYPLOT and FL_LINEPOINTS_XYPLOT are special in that the application can change the symbol drawn on the data point.
