Class BoundsRenderer

java.lang.Object

org.das2.graph.Renderer

org.das2.graph.BoundsRenderer

All Implemented Interfaces:

Displayable, Editable, DataSetConsumer

public class BoundsRenderer
extends Renderer

Draw the region bounded by the dataset. If the dataset is a bounding box, the box is drawn. If the data is a rank 2 time series with bins (N by 2), then it is drawn. This supports the following types:

• bounding box
• array of bounding box
• array of bins

public BoundsRenderer()

Method Detail

acceptsDataSet

public boolean acceptsDataSet(QDataSet ds)

Description copied from class: Renderer

return true if the dataset appears to be in a scheme accepted by this renderer. This should assume that axis units can be reset, etc.

Overrides:

acceptsDataSet in class Renderer

Returns:

true if the dataset appears to be acceptable.

acceptContext

public boolean acceptContext(int x,
                             int y)

Description copied from class: Renderer

Returns true if the render will accept the context for a point. That is, the renderer affected that point, or nearby points. This is used currently to provide a way for the operator to click on a plot and directly edit the renderer which drew the pixel.

Overrides:

acceptContext in class Renderer

Parameters:

x - the x coordinate in the canvas coordinate system.

y - the y coordinate in the canvas coordinate system.

Returns:

true if the renderer will accept the context.

selectionArea

public java.awt.geom.Area selectionArea()

getListIcon

public javax.swing.Icon getListIcon()

Description copied from interface: Displayable

An icon can be provided that will be shown in a list along with the textual description of the element. This method should return null if there is no icon available, or a roughly 16x16 pixel icon.

Specified by:

getListIcon in interface Displayable

Overrides:

getListIcon in class Renderer

Returns:

the icon.

getListLabel

public java.lang.String getListLabel()

Description copied from interface: Displayable

return a String that will help the user identify this item when choosing from a list.

Specified by:

getListLabel in interface Displayable

Overrides:

getListLabel in class Renderer

Returns:

the list label.

doAutorange

public static QDataSet doAutorange(QDataSet ds)

getControl

public java.lang.String getControl()

Description copied from class: Renderer

get the string which summarizes the state of the renderer. These allow a compact string to contain the renderer settings. This should be an ampersand-delimited list of name=value pairs.

Overrides:

getControl in class Renderer

Returns:

setControl

public void setControl(java.lang.String s)

Description copied from class: Renderer

set the control string which contains a number of properties. These are defined for each renderer, but they should try to be consistent. See http://autoplot.org/developer.guessRenderType#Proposed_extensions When overriding this, be sure to call super.

Overrides:

setControl in class Renderer

Parameters:

s - the control

See Also:

etc

getColor

public java.awt.Color getColor()

setColor

public void setColor(java.awt.Color color)

getFillColor

public java.awt.Color getFillColor()

setFillColor

public void setFillColor(java.awt.Color color)

getFillTexture

public java.lang.String getFillTexture()

setFillTexture

public void setFillTexture(java.lang.String fillTexture)

isPolar

public boolean isPolar()

setPolar

public void setPolar(boolean polar)

if true then transform render the data in polar coordinates

Parameters:

polar -

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
