Class MyRenderer

java.lang.Object

org.das2.graph.Renderer

test.graph.MyRenderer

All Implemented Interfaces:

Displayable, Editable, DataSetConsumer

public class MyRenderer
extends Renderer

Demonstration of defining a new Renderer. This can be compiled into the application and then added to the DasPlot. This example Renderer takes a Rank 2 ds[n,4]. Each record is the x and y positions, then the radius, then the color.

Method Detail

render

public void render(java.awt.Graphics g,
                   DasAxis xAxis,
                   DasAxis yAxis,
                   ProgressMonitor mon)

Description copied from class: Renderer

Render is called whenever the image needs to be refreshed or the content has changed. This operation should occur with an animation-interactive time scale, and an image should be cached when this is not possible. The graphics object will have its origin at the upper-left corner of the screen.

Specified by:

render in class Renderer

Parameters:

g - the graphics context in the canvas reference frame.

xAxis - the axis relating x data coordinates to horizontal pixel coordinates

yAxis - the axis relating y data coordinates to horizontal pixel coordinates

mon - a monitor for the operation. Note the render operation should be fast (<300ms).

getScale

public double getScale()

return the scale for the radius

Returns:

the scale for the radius

setScale

public void setScale(double s)

the scale for the radius

Parameters:

s - the scale for the radius

setControl

public void setControl(java.lang.String s)

set the control string.

Overrides:

setControl in class Renderer

Parameters:

s - the control string

See Also:

etc

getControl

public java.lang.String getControl()

get the control string

Overrides:

getControl in class Renderer

Returns:

the control string
