Detailed Description

Abstraction of a axis for a FXPlot2D.

To plot a FXCurve in a FXPlot2D it has to be attached to tow FXAxis. The FXAxis class provides the relation between the data holded by the FXCurve and the pixes that the curve will draw. Furthermore, the FXAxis draws itself on the plot to give scale informations.

Note:

Only linear scale is implemented, logarithimic and etc could be done.

Constructor & Destructor Documentation

FXAxis::FXAxis (  FXPlot2D *  p, FXint  flags = Bottom|Enabled|Linear|MajorThicks )

Constructor. Create a new Axis on the Plot2D p, with a given OrientationType orientation and a flag enable.

Member Function Documentation

double FXAxis::backTransform (  FXint  y  )  const

Backward trasnformation of coordinates (from pixel to double). See also: transform

FXbool FXAxis::contains (  double  value  )  const

Checks if the given point is within the current axis range. See also: setRange

double FXAxis::getMax (   )  const

Return the upper limit of the double range. See also: getMin setRange transform

double FXAxis::getMin (   )  const

Return the lower value of the double range. See also: getMax setRange transform

void FXAxis::setPosition (  FXPoint  p1, FXPoint  p2 )

Set the axis position on the Plot2D. This function should be called by the layout algorithm of the Plot2D. The points given here are used by transform() and to draw the Axis.

void FXAxis::setRange (  double  min, double  max )

Set the range that the Axis will cover. The range is used to transform() a given value to its pixel (integer) equivalent.

void FXAxis::zoomIn (  FXint  x  )

Zomms the axis in around the given point. This function changes the range covered by the axis. See also: setRange.

void FXAxis::zoomOut (  void   )

Zomms the axis out. This function changes the range covered by the axis. See also: zoomIn setRange
