All Implemented Interfaces:

Old renderer that really doesn't do anything that the SeriesRenderer can't do, but is much easier to understand.

Constructor Detail

CurveRenderer

public CurveRenderer(DataSetDescriptor dsd,
                     java.lang.String xplane,
                     java.lang.String yplane)

The dataset descriptor should return a rank 2 QDataSet with time for and a bundle descriptor for BUNDLE_1. DataSetOps.unbundle is used to extract the xplane and yplane components.

Parameters:

dsd - null or the DataSetDescriptor which can load more data.

xplane - the name of the bundled dataset, or null, or ""

yplane - the name of the bundled dataset, or null, or ""

DataSetOps.unbundle(org.das2.qds.QDataSet, java.lang.String)

CurveRenderer

public CurveRenderer()

Constructor for renderer which takes a dataset which is Y(DEPEND_0=X)

Method Detail

render

public void render(java.awt.Graphics2D g1,
                   DasAxis xAxis,
                   DasAxis yAxis)

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:

g1 - 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

updatePlotImage

public void updatePlotImage(DasAxis xAxis,
                            DasAxis yAxis,
                            ProgressMonitor monitor)
                     throws DasException

Description copied from class: Renderer

updatePlotImage is called once the expensive operation of loading the data is completed. This operation should occur on an interactive time scale. This is an opportunity to create a cache image of the data with the current axis state, when the render operation cannot operate on an animation interactive time scale. Also, several Renders can be updating at once on separate threads, while the render methods must be called sequentially. Only Renderer should call this method! (This should be protected then, but this is not possible because of exiting use. TODO: introduce "revalidate" to replace this operation.)

Overrides:

updatePlotImage in class Renderer

Parameters:

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

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

monitor - a monitor for the operation. Note the updatePlotImage operation should be fast (<1000ms).

Throws:

DasException

getLineWidth

public final double getLineWidth()

Getter for property lineWidth.

Returns:

Value of property lineWidth.

setLineWidth

public final void setLineWidth(double lineWidth)

Setter for property lineWidth.

Parameters:

lineWidth - New value of property lineWidth.

getSymSize

public final double getSymSize()

setSymSize

public final void setSymSize(double symSize)

set the symbol size in pixels (ems)

Parameters:

symSize -

getPsymConnector

public PsymConnector getPsymConnector()

setPsymConnector

public void setPsymConnector(PsymConnector p)

set the type of line connecting plot symbols (e.g. solid, none, dotted).

Parameters:

p -

getPsym

public final Psym getPsym()

Getter for property psym.

Returns:

Value of property psym.

setPsym

public final void setPsym(Psym psym)

Setter for property psym.

Parameters:

psym - New value of property psym.

getColor

public java.awt.Color getColor()

setColor

public void setColor(java.awt.Color color)

setter for the property color.

Parameters:

color -
