org.autoplot.dom.PlotElementController

PlotElementController manages the PlotElement, for example resolving the datasource and loading the dataset. Once the data is loaded, the listening PlotElementController receives the update and does the following:

resolve the plot type: spectrogram, lineplot, stack of lineplot, etc, using AutoplotUtil.guessRenderType(fillDs);
reset the plot element, setting the plot type and creating children if needed. For example, a B-GSM (demo 5) is resolved by creating three children, and handing the components off to them.
if the component property is not empty, then we implement the component and display that.
adjusting the component slice index will not affect ranging when the index is changed.

PlotElementController( org.autoplot.ApplicationModel model, org.autoplot.dom.Application dom, org.autoplot.dom.PlotElement plotElement )

SYMSIZE_DATAPOINT_COUNT

switch over between fine and course points.

LARGE_DATASET_COUNT

PROP_DATASET

the current dataset plotted, after operations (component property) has been applied.

PROP_RESETRANGES

true indicates the controller should autorange next time the fillDataSet is changed.

PROP_RESETPLOTELEMENT

true indicates the controller should install a new renderer to implement the renderType selection. This may mean that we introduce or remove child plotElements. This implies resetRenderType.

PROP_RESETCOMPONENT

true indicates that the component should be reset when the dataset arrives. This is added as a controller property so that clients can clear this setting if they do not want the component to be reset. This is only considered if resetPlotElement is set.

PROP_RESETRENDERTYPE

true indicates the peer should be reset to the current renderType.

PROP_DSFRESET

when true, a change in the DataSourceFilter should reset the plotElement.

PROP_SLICEAUTORANGES

axisDimensionsChange

axisDimensionsChange( org.autoplot.RenderType oldRenderType, org.autoplot.RenderType newRenderType ) → boolean

true indicates that the new renderType makes the axis dimensions change. For example, switching from spectrogram to series (to get a stack of components) causes the z axis to become the yaxis.

Parameters

oldRenderType - a RenderType
newRenderType - a RenderType

Returns:

true if the dimensions change.

doAutoranging

doAutoranging( org.autoplot.dom.PlotElement peleCopy, java.util.Map props, QDataSet fillDs ) → void

This is the old updateFillSeries and updateFillSpectrogram code. This calculates ranges and preferred symbol settings, and puts the values in peleCopy.plotDefaults. The dom Plot containing this plotElement should be listening for changes in plotElement.plotDefaults, and can then decide if it wants to use the autorange settings. This also sets the style node of the plotElement copy, so its values should be sync'ed as well.

Parameters

peleCopy - the plot element.
props - metadata provided by the data source, converted to uniform QDataSet scheme (e.g. get(DEPEND_0).get(TYPICAL_MIN) )
fillDs - the dataset

Returns:

void (returns nothing)

doAutoranging( org.autoplot.dom.PlotElement peleCopy, java.util.Map props, QDataSet fillDs, boolean ignoreDsProps ) → void

doResetRenderType

doResetRenderType( org.autoplot.RenderType renderType ) → void

used to explicitly set the rendering type. This installs a das2 renderer into the plot to implement the render type. preconditions: renderer type has been identified. postconditions: das2 renderer peer is created and bindings made.

Parameters

renderType - a RenderType

Returns:

void (returns nothing)
