Member Enumeration Documentation

enum FXCurve::CurveStyle

FXCurve styles. See also: setStyle. Definition at line 147 of file FXCurve.h.

Constructor & Destructor Documentation

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

Constructor for a curve memory x and y. The FXCurve will delete the given FXCurveData pointers when destructing the curve.

Member Function Documentation

virtual void FXCurve::drawMarks (  FXDC *  dc  )  const [protected, virtual]

Draw the marks of the curve. This function is called by drawSelf() and can be overloaded to get a different behaviour. See also: drawMark

void FXCurve::drawSample (  FXDC *  p, FXint  x, FXint  y, FXbool  line = false )  const

Draws one point of the curve at a given point. This function is used to draw the legend. See also: drawMark

virtual void FXCurve::drawSteps (  FXDC *  dc  )  const [protected, virtual]

Draw a step line curve for the current points. This function is called by drawSelf() and can be overloaded to get a different behaviour.

void FXCurve::setAxis (  FXAxis *  x, FXAxis *  y )

Sets the axis for the curve. The calculation of the points of a curve are based on the axis.

void FXCurve::update (   )  [inline]

Schedule a calculation for the curve. This function is called when zooming, or if the axis has changed. Definition at line 278 of file FXCurve.h. References calculated.
