Hi all!
I have problems generating a meter chart with multiple datasets via API (3.7.1). The interesting part of my class looks like:
protected void buildSeries() {
String[] x = new String[] { "A", "B", "C"};
Double[] y = new Double[] { 20.0, 30.0, 40.0 };
TextDataSet categoryValues = TextDataSetImpl.create(x);
NumberDataSet seriesValues = NumberDataSetImpl.create(y);
// Base Series
SeriesDefinition sd = SeriesDefinitionImpl.create();
((ChartWithoutAxes) chart).getSeriesDefinitions().add(sd);
Series seCategory = (Series) SeriesImpl.create();
seCategory.setDataSet(categoryValues);
sd.getSeriesPalette().shift(0);
sd.getSeries().add(seCategory);
// Orthogonal Series
for (int i = 0; i < y.length; i++) {
SeriesDefinition sdY = SeriesDefinitionImpl.create();
sd.getSeriesDefinitions().add(sdY);
DialSeries ds = (DialSeries) DialSeriesImpl.create();
ds.setDataSet(seriesValues);
sdY.getSeries().add(ds);
}
}
But as a result, only the first dataset "A" is visible, despite the fact that the whole plot ranges from 0.0 to 40.0, so somehow the other data is only considered for displaying the range.
How can I change my method in order to have one dialplot with several pointers?
Thank you very much! (:

Chris,
Are you intentionally trying to create three dial series with the same data?
Do you want three meter charts or one meter chart with 3 dials. Look at
this example from the source:
public static final Chart highlight_MeterChart( )
{
DialChart dChart = (DialChart) DialChartImpl.create( );
dChart.setDialSuperimposition( false );
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( false );
p.getOutline( ).setVisible( false );
dChart.getTitle( ).getLabel( ).getCaption( ).setValue( "Meter Chart" );
dChart.getTitle( ).getOutline( ).setVisible( false );
// Legend
Legend lg = dChart.getLegend( );
LineAttributes lia = lg.getOutline( );
lg.getText( ).getFont( ).setSize( 16 );
lia.setStyle( LineStyle.SOLID_LITERAL );
lg.getInsets( ).setLeft( 10 );
lg.getInsets( ).setRight( 10 );
lg.setBackground( null );
lg.getOutline( ).setVisible( false );
lg.setShowValue( true );
lg.getClientArea( ).setBackground( ColorDefinitionImpl.PINK( ) );
lg.getClientArea( ).getOutline( ).setVisible( true );
lg.getTitle( ).getCaption( ).getFont( ).setSize( 20 );
lg.getTitle( ).setInsets( InsetsImpl.create( 10, 10, 10, 10 ) );
lg.setTitlePosition( Position.ABOVE_LITERAL );
lg.setPosition( Position.BELOW_LITERAL );
lg.setItemType( LegendItemType.SERIES_LITERAL );
lg.getTriggers( ).add(
TriggerImpl.create(
TriggerCondition.ONCLICK_LITERAL,
ActionImpl.create(
ActionType.HIGHLIGHT_LITERAL,
SeriesValueImpl.create( "not-used" ) ) ) ); //$NON-NLS-1$
TextDataSet categoryValues = TextDataSetImpl
.create( new String[]{"Moto"} );
SeriesDefinition sd = SeriesDefinitionImpl.create( );
dChart.getSeriesDefinitions( ).add( sd );
Series seCategory = (Series) SeriesImpl.create( );
seCategory.setDataSet( categoryValues );
sd.getSeries( ).add( seCategory );
SeriesDefinition sdCity = SeriesDefinitionImpl.create( );
final Fill[] fiaOrth = {ColorDefinitionImpl.PINK( ),
ColorDefinitionImpl.ORANGE( ), ColorDefinitionImpl.WHITE( )};
sdCity.getSeriesPalette( ).getEntries( ).clear( );
for ( int i = 0; i < fiaOrth.length; i++ )
{
sdCity.getSeriesPalette( ).getEntries( ).add( fiaOrth[i] );
}
