Chart SDK 3.7.2 - suddenly my marker lines and colors gone?! [message #808402]

Hi,

just yesterday I switched my RCP project from the Chart SDK 3.7.1 to 3.7.2.

No I am experiencing some differences in the line charts (the pie charts are okay), in particular
* the marker lines are gone
* the assigned colors are not used anymore

First, the marker lines are not rendered anymore. This is how I do it:

   public LineChartBuilder addMarkerLine(Date date, ColorDefinition color, String label)
    {
        Axis xAxis = chart.getPrimaryBaseAxes()[0];
        MarkerLine ml = MarkerLineImpl.create(xAxis,
                DateTimeDataElementImpl.create(new CDateTime(date)));
        ml.getLineAttributes().setStyle(LineStyle.SOLID_LITERAL);
        ml.getLineAttributes().setColor(color);
        ml.setLabelAnchor(Anchor.SOUTH_EAST_LITERAL);
        ml.getLabel().getCaption().setValue(label);
        return this;
    }

Second, the colors that I assign to the lines are not recognized anymore:

    private void addYLineSeries(ColorDefinition color, NumberDataSet dataSet)
    {
        LineSeries ls = (LineSeries) LineSeriesImpl.create();
        ls.setDataSet(dataSet);
        ls.setStacked(false);
        ls.getLineAttributes().setColor(color);
        ls.getLineAttributes().setThickness(3);
        ls.getLabel().setVisible(false);

        for (int i = 0; i < ls.getMarkers().size(); i++)
            ((Marker) ls.getMarkers().get(i)).setVisible(false);

        SeriesDefinition sdY = SeriesDefinitionImpl.create();
        sdY.getSeries().add(ls);
        yAxis.getSeriesDefinitions().add(sdY);
    }

Any idea what changed between Chart SDK 3.7.1 and Chart SDK 3.7.2 and what I need to do to fix this?

I appreciate any hint where to go looking.

Can you hard code your MarkerLine using a NumberDataElementImpl as a
test? Like:

protected static final Chart createChart_Marker( )
{
ChartWithAxes cwaBar = ChartWithAxesImpl.create( );
Locale.setDefault( Locale.US );
cwaBar.setScript( "function beforeDrawMarkerLine(axis, line,
scriptContext)" //$NON-NLS-1$
+ "{ importPackage(Packages.java.util);" //$NON-NLS-1$
+ "if (scriptContext.getLocale().equals(Locale.US))" //$NON-NLS-1$
+ "{line.getLabel().getCaption( ).getColor().set( 165, 184, 55 );"
//$NON-NLS-1$
+ "line.getLineAttributes().getColor().set( 165, 184, 55 );}}"
//$NON-NLS-1$

+ "function beforeDrawMarkerRange(axis, range, scriptContext)"
//$NON-NLS-1$
+ "{range.getLabel().getCaption().getColor().set( 225, 104, 105
);}" //$NON-NLS-1$
);

// X-Axis
Axis xAxisPrimary = cwaBar.getPrimaryBaseAxes( )[0];
xAxisPrimary.setType( AxisType.TEXT_LITERAL );
xAxisPrimary.getOrigin( ).setType( IntersectionType.VALUE_LITERAL );

// Y-Axis
Axis yAxisPrimary = cwaBar.getPrimaryOrthogonalAxis( xAxisPrimary );
yAxisPrimary.getMajorGrid( ).setTickStyle( TickStyle.LEFT_LITERAL );
yAxisPrimary.setType( AxisType.LINEAR_LITERAL );

MarkerLine ml = MarkerLineImpl.create( yAxisPrimary,
NumberDataElementImpl.create( 2 ) );
yAxisPrimary.getMarkerLines( ).add( ml );

MarkerRange mr = MarkerRangeImpl.create( yAxisPrimary,
NumberDataElementImpl.create( 8 ),
NumberDataElementImpl.create( 12 ),
ColorDefinitionImpl.PINK( ) );
yAxisPrimary.getMarkerRanges( ).add( mr );

// Data Set
TextDataSet categoryValues = TextDataSetImpl.create( new String[]{
"Item 1", "Item 2", "Item 3"} ); //$NON-NLS-1$ //$NON-NLS-2$
//$NON-NLS-3$
NumberDataSet orthoValues = NumberDataSetImpl.create( new double[]{
8, 18, -15
} );

// X-Series
Series seCategory = SeriesImpl.create( );
seCategory.setDataSet( categoryValues );

SeriesDefinition sdX = SeriesDefinitionImpl.create( );
xAxisPrimary.getSeriesDefinitions( ).add( sdX );
sdX.getSeries( ).add( seCategory );

// Y-Series
BarSeries bs = (BarSeries) BarSeriesImpl.create( );
bs.setDataSet( orthoValues );
bs.getLabel( ).setVisible( true );

SeriesDefinition sdY = SeriesDefinitionImpl.create( );
yAxisPrimary.getSeriesDefinitions( ).add( sdY );
sdY.getSeries( ).add( bs );

return cwaBar;
}

Hi Jason,

thanks for your answer. I appreciate your quick reply.

Your example runs fine within my program.

Then I adapted your example to demonstrate the two problems I have (see also attached screenshot). The full code is pasted below.

index.php/fa/7341/0/

First, the marker lines are not shown.

        MarkerLine ml = MarkerLineImpl.create(xAxisPrimary, DateTimeDataElementImpl.create(new CDateTime(2010, 2, 1)));
        ml.getLineAttributes().setStyle(LineStyle.SOLID_LITERAL);
        ml.getLineAttributes().setColor(ColorDefinitionImpl.PINK());
        ml.getLabel().getCaption().setValue("Some marker");
        xAxisPrimary.getMarkerLines().add(ml);

Second, the line color stays blue (even though the line markers are green). Interesting, the thickness of the line can be changed, but not the color.

        ls.getLineAttributes().setColor(ColorDefinitionImpl.GREEN());
        ls.getLineAttributes().setThickness(3);

Any hints?

    protected static final Chart buildChart()
    {
        ChartWithAxes cwaBar = ChartWithAxesImpl.create();

        // X-Axis
        Axis xAxisPrimary = cwaBar.getPrimaryBaseAxes()[0];
        xAxisPrimary.setType(AxisType.DATE_TIME_LITERAL);
        xAxisPrimary.getOrigin().setType(IntersectionType.VALUE_LITERAL);

        // Y-Axis
        Axis yAxisPrimary = cwaBar.getPrimaryOrthogonalAxis(xAxisPrimary);
        yAxisPrimary.getMajorGrid().setTickStyle(TickStyle.LEFT_LITERAL);
        yAxisPrimary.setType(AxisType.LINEAR_LITERAL);

        // marker line
        MarkerLine ml = MarkerLineImpl.create(xAxisPrimary, DateTimeDataElementImpl.create(new CDateTime(2010, 2, 1)));
        ml.getLineAttributes().setStyle(LineStyle.SOLID_LITERAL);
        ml.getLineAttributes().setColor(ColorDefinitionImpl.PINK());
        ml.getLabel().getCaption().setValue("Some marker");
        xAxisPrimary.getMarkerLines().add(ml);

        // Data Set
        DateTimeDataSet categoryValues = DateTimeDataSetImpl.create(new CDateTime[] { new CDateTime(2010, 1, 1),
                        new CDateTime(2010, 2, 1), new CDateTime(2010, 3, 1) });

        NumberDataSet orthoValues = NumberDataSetImpl.create(new double[] { 8, 18, -15 });

        // X-Series
        Series seCategory = SeriesImpl.create();
        seCategory.setDataSet(categoryValues);

        SeriesDefinition sdX = SeriesDefinitionImpl.create();
        xAxisPrimary.getSeriesDefinitions().add(sdX);
        sdX.getSeries().add(seCategory);

        // Y-Series
        LineSeries ls = (LineSeries) LineSeriesImpl.create();
        ls.setDataSet(orthoValues);
        ls.setStacked(false);
        ls.getLineAttributes().setColor(ColorDefinitionImpl.GREEN());
        ls.getLineAttributes().setThickness(3);
        ls.getLabel().setVisible(true);

        SeriesDefinition sdY = SeriesDefinitionImpl.create();
        yAxisPrimary.getSeriesDefinitions().add(sdY);
        sdY.getSeries().add(ls);

        return cwaBar;
    }

Try adding:

xAxisPrimary.setCategoryAxis(false);

and
ls.setPaletteLineColor(false);

revised code below

protected static final Chart createChart_Marker( )
{
ChartWithAxes cwaBar = ChartWithAxesImpl.create();

// X-Axis
Axis xAxisPrimary = cwaBar.getPrimaryBaseAxes()[0];
xAxisPrimary.setType(AxisType.DATE_TIME_LITERAL);
xAxisPrimary.getOrigin().setType(IntersectionType.MIN_LITERAL);
xAxisPrimary.setCategoryAxis(false);

// Y-Axis
Axis yAxisPrimary = cwaBar.getPrimaryOrthogonalAxis(xAxisPrimary);
yAxisPrimary.getMajorGrid().setTickStyle(TickStyle.LEFT_LITERAL);
yAxisPrimary.setType(AxisType.LINEAR_LITERAL);

// marker line
MarkerLine ml = MarkerLineImpl.create(xAxisPrimary,
DateTimeDataElementImpl.create(new CDateTime(2010, 2, 1)));
ml.getLineAttributes().setStyle(LineStyle.SOLID_LITERAL);
ml.getLineAttributes().setColor(ColorDefinitionImpl.PINK());
ml.getLabel().getCaption().setValue("Some marker");
xAxisPrimary.getMarkerLines().add(ml);

// Data Set
DateTimeDataSet categoryValues = DateTimeDataSetImpl.create(new
CDateTime[] { new CDateTime(2010, 1, 1),
new CDateTime(2010, 2, 1), new CDateTime(2010,
3, 1) });

NumberDataSet orthoValues = NumberDataSetImpl.create(new
double[] { 8, 18, -15 });

// X-Series
Series seCategory = SeriesImpl.create();
seCategory.setDataSet(categoryValues);

SeriesDefinition sdX = SeriesDefinitionImpl.create();
xAxisPrimary.getSeriesDefinitions().add(sdX);
sdX.getSeries().add(seCategory);

// Y-Series
LineSeries ls = (LineSeries) LineSeriesImpl.create();
ls.setDataSet(orthoValues);
ls.setStacked(false);
ls.setPaletteLineColor(false);
ls.getLineAttributes().setColor(ColorDefinitionImpl.RED());
ls.getLineAttributes().setThickness(3);
ls.getLabel().setVisible(true);

SeriesDefinition sdY = SeriesDefinitionImpl.create();
yAxisPrimary.getSeriesDefinitions().add(sdY);
sdY.getSeries().add(ls);

return cwaBar;
}
