Method Detail

getLineThick

public java.lang.String getLineThick()

setLineThick

public void setLineThick(java.lang.String lineThick)

doAutorange

public static QDataSet doAutorange(QDataSet ds)

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.

setDataSet

public void setDataSet(QDataSet ds)

Description copied from class: Renderer

Set the dataset to be plotted. Different renderers accept QDataSets with different schemes. For example SeriesRenderer takes: ds[t] rank 1 dataset with rank 1 DEPEND_0 or ds[t,n] rank 2 bundle dataset with X in ds[t,0] and Y in ds[t,n-1] and SpectrogramRenderer takes: ds[t,y] rank 2 table dataset ds[n,t,y] rank 3 dataset with the first dimension join See each renderer's documentation for the schemes it takes. Note the lastException property is cleared, even when the dataset is null.

Overrides:

setDataSet in class Renderer

render

public void render(java.awt.Graphics2D g,
                   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:

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
