Hi,
I can not see the meter chart. It only show the backgroung plot color.It
did not show the chart.
I have given the code.
public static final Chart createSDialSRegionChart() {
DialChart dChart = (DialChart) DialChartImpl.create();
dChart.setDialSuperimposition(true);
dChart.setGridColumnCount(2);
dChart.setSeriesThickness(25);
// Title/Plot
dChart.getBlock().setBackground(ColorDefinitionImpl.WHITE()) ;
Plot p = dChart.getPlot();
p.getClientArea().setBackground(ColorDefinitionImpl.CREAM()) ;
p.getClientArea().getOutline().setVisible(true);
p.getOutline().setVisible(true);
dChart.getTitle().getLabel().getCaption().setValue("Meter Chart");
dChart.getTitle().getOutline().setVisible(true);
// Legend
Legend lg = dChart.getLegend();
LineAttributes lia = lg.getOutline();
lg.getText().getFont().setSize(6);
lia.setStyle(LineStyle.SOLID_LITERAL);
lg.getInsets().setLeft(5);
lg.getInsets().setRight(5);
lg.setBackground(null);
lg.getOutline().setVisible(true);
lg.setShowValue(true);
lg.getClientArea().setBackground(ColorDefinitionImpl.PINK()) ;
lg.getClientArea().getOutline().setVisible(true);
lg.getTitle().getCaption().getFont().setSize(8);
lg.getTitle().setInsets(InsetsImpl.create(10, 10, 10, 10));
lg.setTitlePosition(Position.ABOVE_LITERAL);
// Data Set
TextDataSet categoryValues = TextDataSetImpl
.create(new String[] { "Speed" });
SeriesDefinition sd = SeriesDefinitionImpl.create();
dChart.getSeriesDefinitions().add(sd);
Series seCategory = (Series) SeriesImpl.create();
final Fill[] fiaBase = {
ColorDefinitionImpl.ORANGE(),
GradientImpl.create(ColorDefinitionImpl.create(225, 225, 255),
ColorDefinitionImpl.create(255, 255, 225), -35, false),
ColorDefinitionImpl.RED(), ColorDefinitionImpl.RED(),
ColorDefinitionImpl.GREEN(),
ColorDefinitionImpl.BLUE().brighter(),
ColorDefinitionImpl.CYAN().darker(), };
sd.getSeriesPalette().getEntries().clear();
for (int i = 0; i < fiaBase.length; i++) {
System.out.println("========fiaBase[i]=========="+fiaBase[i]);
sd.getSeriesPalette().getEntries().add(fiaBase[i]);
}
seCategory.setDataSet(categoryValues);
sd.getSeries().add(seCategory);
SeriesDefinition sdCity = SeriesDefinitionImpl.create();
// Dial
DialSeries seDial = (DialSeries) DialSeriesImpl.create();
seDial.setDataSet(NumberDataSetImpl.create(new double[] { 60 }));
seDial.getDial().setFill(
GradientImpl.create(ColorDefinitionImpl.create(225, 225, 255),
ColorDefinitionImpl.create(255, 255, 225), -35, false));
seDial.getNeedle().setDecorator(LineDecorator.ARROW_LITERAL) ;
seDial.getDial().getMinorGrid().getTickAttributes().setVisib le(true);
seDial.getDial().getMinorGrid().getTickAttributes().setColor (
ColorDefinitionImpl.RED());
seDial.getDial().getMinorGrid().setTickStyle(TickStyle.BELOW _LITERAL);
seDial.getDial().getScale().setMin(NumberDataElementImpl.cre ate(0));
seDial.getDial().getScale().setMax(NumberDataElementImpl.cre ate(180));
seDial.getDial().getScale().setStep(30);
seDial.getLabel().setOutline(
LineAttributesImpl.create(ColorDefinitionImpl.GREY().darker( ),
LineStyle.SOLID_LITERAL, 1));
seDial.getLabel().setBackground(ColorDefinitionImpl.GREY().b righter());
DialRegion dregion21 = DialRegionImpl.create();
dregion21.setFill(ColorDefinitionImpl.GREEN());
dregion21.setStartValue(NumberDataElementImpl.create(0));
dregion21.setEndValue(NumberDataElementImpl.create(80));
seDial.getDial().getDialRegions().add(dregion21);
sd.getSeriesDefinitions().add(sdCity);
sdCity.getSeries().add(seDial);
return dChart;
}
can any one help me?

Did you try the DialChartViewer code in the org.eclipse.birt.chart.example
plugin? It works for me for all dial charts (one of them is very similar to
the code you posted).
Thanks,
David

Also i have given the program code bellow:--

BufferedImage bi = new BufferedImage( (int) bo.getWidth( ), (int)
bo.getHeight( ), BufferedImage.TYPE_INT_ARGB );
try{
IDeviceRenderer idr = PluginSettings.instance( ) .getDevice(
"dv.PNG" );
bo.scale(72d / idr.getDisplayServer().getDpiResolution());
Chart cm1 = createSDialSRegionChart();
cm1.setDimension(ChartDimension.TWO_DIMENSIONAL_LITERAL);
RunTimeContext rtc = new RunTimeContext( );
rtc.setLocale( Locale.getDefault( ) );
Generator gr1 = Generator.instance( );
GeneratedChartState gcs1 = null;
gcs1 = gr1.build( idr.getDisplayServer( ), cm1, null, bo, rtc
);
idr.setProperty( IDeviceRenderer.GRAPHICS_CONTEXT,
bi.getGraphics() );

}
catch (ChartException x)
{
