Detailed Description

Class for visualizing FXCurve's in a 2D plot.

The FXPlot2D class can be used to show FXCurve's in a 2D way. Are provided methods for zooming.

The plot has four FXAxis, each one represented by the class FXAxis. Each FXCurve is related to two different FXAxis.

New curves can be added to the plot by the addCurve() methods and can be removed with removeCurve().

FXAxis and FXCurve.

Member Function Documentation

void FXPlot2D::addCurve (  FXCurve *  FXCurve  )

Add a new FXCurve to the plot. This function adds FXCurve to the plot and set the FXAxis of this FXCurve to Bottom and Right. See also: FXCurve and FXAxis.

FXCurve* FXPlot2D::addCurve (  const FXString &  label, FXCurveData *  x, FXCurveData *  y, FXCurve::CurveStyle  style = FXCurve::Lines )

Create a new FXCurve. This function new FXCurve named name, given the vectors x and and add it to the Plot2D with the function addCurve(FXCurve *FXCurve);

void FXPlot2D::removeAllCurves (   )

Remove all curves deleting them. This function is equivalent to call removeCurve() for all curves.

void FXPlot2D::removeCurve (  FXCurve *  FXCurve, FXbool  del = TRUE )

Remove the FXCurve FXCurve. If del is TRUE the curve is deleted.

void FXPlot2D::updateCurves (  void   )  [protected]

Mark all the FXCurve's of this plot as not calculated. When redimensioning or zooming the plot the curves became invalid, so this function is called.
