virtual long firstX ( double  x1, double  x2  ) const

pure virtual

The index of the first column in the x-range x1, x2.

virtual long lastX ( double  x1, double  x2  ) const

pure virtual

The index of the last column in the x-range x1, x2.

virtual long firstY ( double  y1, double  y2  ) const

pure virtual

The index of the first row in the y-range y1, y2.

virtual long lastY ( double  y1, double  y2  ) const

pure virtual

The index of the last column in the y-range y1, y2.

virtual void point ( long  rindex, long  cindex, double &  x1, double &  y1, double &  x2, double &  y2, double &  z  ) const

pure virtual

Returns in x1, y1, x2, and y2 the rectangle that gets the value z of the data point at row index rindex and column index\ a cindex.

virtual bool init ( void  )

inlinevirtual

Can be reimplemented for some initialization before initializing and drawing the plot.

Returns

true if the data changed

virtual void xminmax ( double &  xmin, double &  xmax, double  ymin, double  ymax  ) const

inlinevirtual

Returns a sensible x-range xmin and xmax for a given y-range ymin, ymax.

virtual void yminmax ( double  xmin, double  xmax, double &  ymin, double &  ymax  ) const

inlinevirtual

Returns a sensible y-range ymin and ymax for a given x-range xmin, xmax.

virtual void setRange ( double  xmin[MaxAxis], double  xmax[MaxAxis], double  ymin[MaxAxis], double  ymax[MaxAxis], int  xpmin, int  xpmax, int  ypmin, int  ypmax  )

inlinevirtual

Passes the current ranges and pixel positions to the data element after initializing but before drawing the plot.
