C# Class NPlot.ImagePlot

Encapsulates functionality for plotting data as a 2D image chart.

Inheritance: IPlot

Public Methods

Method	Description
Draw ( Graphics g, PhysicalAxis xAxis, PhysicalAxis yAxis ) : void	Draw on to the supplied graphics surface against the supplied axes. TODO: block positions may be off by a pixel or so. maybe. Re-think calculations
DrawInLegend ( Graphics g, Rectangle startEnd ) : void	Draws a representation of this plot in the legend.
ImagePlot ( double data ) : System	Constructor
ImagePlot ( double data, double xStart, double xStep, double yStart, double yStep ) : System	Constructor no adapters for this yet - when we get some more 2d plotting functionality, then perhaps create some.
SuggestXAxis ( ) : Axis	Returns an x-axis that is suitable for drawing this plot.
SuggestYAxis ( ) : Axis	Returns a y-axis that is suitable for drawing this plot.
WriteData ( System sb, RectangleD region, bool onlyInRegion ) : void	Write data associated with the plot as text. TODO: not implemented.

Method	Description
calculateMinMax ( ) : void	Calculates the minimum and maximum values of the data array.

Draw on to the supplied graphics surface against the supplied axes.

TODO: block positions may be off by a pixel or so. maybe. Re-think calculations

public Draw ( Graphics g, PhysicalAxis xAxis, PhysicalAxis yAxis ) : void
g	System.Drawing.Graphics	The graphics surface on which to draw.
xAxis	PhysicalAxis	The X-Axis to draw against.
yAxis	PhysicalAxis	The Y-Axis to draw against.
return	void

Draws a representation of this plot in the legend.

public DrawInLegend ( Graphics g, Rectangle startEnd ) : void
g	System.Drawing.Graphics	The graphics surface on which to draw.
startEnd	System.Drawing.Rectangle	A rectangle specifying the bounds of the area in the legend set aside for drawing.
return	void

Constructor

public ImagePlot ( double data ) : System
data	double	The 2D array to plot.
return	System

Constructor

no adapters for this yet - when we get some more 2d plotting functionality, then perhaps create some.

public ImagePlot ( double data, double xStart, double xStep, double yStart, double yStep ) : System
data	double	the 2D array to plot
xStart	double	the world value corresponding to the 1st position in the x-direction
xStep	double	the world step size between pixels in the x-direction.
yStart	double	the world value corresponding to the 1st position in the y-direction
yStep	double	the world step size between pixels in the y-direction.
return	System

Returns an x-axis that is suitable for drawing this plot.

public SuggestXAxis ( ) : Axis
return	Axis

Returns a y-axis that is suitable for drawing this plot.

public SuggestYAxis ( ) : Axis
return	Axis

Write data associated with the plot as text.

TODO: not implemented.

public WriteData ( System sb, RectangleD region, bool onlyInRegion ) : void
sb	System	the string builder to write to.
region	RectangleD	Only write out data in this region if onlyInRegion is true.
onlyInRegion	bool	If true, only data in region is written, else all data is written.
return	void
