Hello,

I create a PieChart in a view like this :
public constructorDemaclass(){
  ...
  produceChart();
}

public Chart produceChart(){
{
  ...
  objectsCODE[0] = new DataObject("CODE", "startup", 32.);
  objectsCODE[1] = new DataObject("CODE", "thandlers", 408.);
  objectsCODE[2] = new DataObject("CODE", "text", 152560.);
  PieChartCode = new PieChartFactory(objectsCODE, labelField, null);
  chart1 = PieChartCode.producePieChart(null, "CODE");
  ...
}
}

public void createPartControl(Composite parent) {
  cParent = parent;
  try {
    paintCanvas = new Canvas( parent, SWT.BORDER |SWT.V_SCROLL );
    paintCanvas.getVerticalBar().setEnabled(false);
    paintCanvas.setLayoutData( new GridData( GridData.FILL_BOTH ) );
    paintCanvas.setBackground( Display.getDefault( ).getSystemColor( SWT.COLOR_WHITE ) );
    chartViewer = new ChartViewer( );
    paintCanvas.addPaintListener( chartViewer );
    paintCanvas.addControlListener( chartViewer );
    chartViewer.setViewer( paintCanvas );
    
    createActions(parent);
    IActionBars actionBars = getViewSite().getActionBars();
    initToolBar(actionBars.getToolBarManager());
    
    chartViewer.renderModel(chart1);
    saveChartAction.setChart(chart1);
    saveChartAction.setBounds(chartViewer.getBounds());
    saveXMLAction.setChart(chart1);
    
    if (chart instanceof ChartWithoutAxes){
      valueSeriesDetailsAction = new  ValueSeriesDetailsAction(this);
      getViewSite().getActionBars().getToolBarManager().add(valueSeriesDetailsAction);
    }
    else {
      coloredByAction = new ColoredByAction(this);
      getViewSite().getActionBars().getToolBarManager().add(coloredByAction);
    }			
    getViewSite().getActionBars().getToolBarManager().update(true);
  
  } catch (Throwable _)
  {
    Status s = new Status(
    Status.ERROR,
    Activator.PLUGIN_ID,
    Status.ERROR,
    "Error when creating AWT Frame...",
    _);
    Activator.getDefault().getLog().log(s);
  }
}

public Chart producePieChart(IChartField valField,String title)

  cwoaPie.setSeriesThickness( 20 );
  cwoaPie.getBlock( ).setBackground( ColorDefinitionImpl.WHITE( ) );
  //cwoaPie.getBlock( ).setBounds(BoundsImpl.create(0,0,252,288));
  Bounds bd = cwoaPie.getBlock( ).getBounds();
  cwoaPie.setDimension(ChartDimension.TWO_DIMENSIONAL_WITH_DEPTH_LITERAL);
  
  // Plot

  p.getClientArea( ).setBackground( null );
  p.getClientArea( ).getOutline( ).setVisible( false );
  
  // Legend

  lg.getOutline( ).setVisible( false );
  lg.getText( ).getFont( ).setSize( 8 );

  }
  int nbData = sectSize.GetNbData();
  for(int i = 0; i<nbData; i++)

  sePie.setExplosion(2);
  sePie.setDataSet( Values );
  sePie.getLabel().getCaption().getFont().setSize(8);		    
  sePie.setLeaderLineStyle(LeaderLineStyle.FIXED_LENGTH_LITERAL);
  sePie.setLeaderLineLength(15);
  
  DataPointComponent dpc = DataPointComponentImpl.create( DataPointComponentType.ORTHOGONAL_VALUE_LITERAL,JavaNumberFormatSpecifierImpl.create( "###.###,00" ) );
  sePie.getDataPoint( ).getComponents( ).clear( );
  sePie.getDataPoint( ).getComponents( ).add( dpc );
  
  //By default the title of the Value Series is not visible
  sePie.getTitle().setVisible(false);	
  //Mouse over the Serie to Show Tooltips
  setTriggering(sePie,lg);	
  sdValue.getSeries( ).add( sePie);
  
  return cwoaPie;
}



It works very well Smile
but I want, in a event, to update the PieChart with new datas.
I try to modify directly the collections of datas but no Sad it dosen't work !

Have you an idea ??
Many thanks !!!

Hello,

I'll try to run your example, and do retro-engeniering to understand.
How do you launch your SwtLiveChartViewer class, by a RCP appli with a view ?
I always do plugins launch under eclipse and never a standalone appli.

So sorry if my question is stupid Sad
and thank you for your help !

That example has a main that can launch it in a shell, or it can be tied
into a view like:

public void createPartControl(Composite parent) {

c3dViewer = new SwtLiveChartViewer( parent, SWT.NO_BACKGROUND );
c3dViewer.setLayoutData( new GridData( GridData.FILL_BOTH ) );
c3dViewer.addPaintListener( c3dViewer );

Ok, I replace the main by your code.
but I've had an error on :
gcs = gr.build( idr.getDisplayServer( ), cm, bo, null, null, null );

It says me : "The type org.mozilla.javascript.Scriptable cannot be resolved. It is indirectly referenced from required .class files"
so I've replaced by :
gcs = gr.build(idr.getDisplayServer( ), cm, bo, null);

I dont understand why but It's ok.
when I execute I've an exception on :
idr.setProperty( IDeviceRenderer.GRAPHICS_CONTEXT, gcImage );

the exception is in the EventTable class on the sendEvent function.
I 've never pass the setProperty method Sad

Do you have an idea ?

In fact, in the method sendEvent, the event type is = 27 or the second time =41 and :
if (types [i] == event.type) {

is never true ....

euh ... an idea ?

What libs from BIRT do you have in your classpath? The js.jar is
available in the birt runtime download. The Scriptable class is in that
jar.

birt-runtime-version\ReportEngine\lib

You either have to use the libs from the BIRT runtime or the libs from
the chart engine download birt-charts-2_5_2\DeploymentRuntime\ChartEngine
