Same shape in line chart

 I have a line chart in the report. Each point in the chart is marked with a shape (isShowShapes is true). By default Jasper Report assigns different shapes to each set of axis. I want to apply same shape to all of them (colors will be different). How can that be achieved?

You can use a chart customizer for that.  It would do something like the following.  Consult the JFreeChart APIs for more information on their classes.

XYLineAndShapeRenderer renderer = (XYLineAndShapeRenderer) ((XYPlot) chart.getPlot()).getRenderer();Shape firstShape = renderer.getSeriesShape(0);renderer.setSeriesShape(1, firstShape);//etc

 Hi.

Is there a way to customize the size? I mean, my chart creates squares as shapes, but they are too big. How can I make them smaller?

I am using this code:

  public void customize( JFreeChart jFreeChart, JRChart jrChart ) {

    XYPlot xyPlot = ( XYPlot )jFreeChart.getPlot();

    XYSplineRenderer splineRenderer = new XYSplineRenderer();

    splineRenderer.setSeriesShapesVisible( 1, false );

    splineRenderer.setSeriesLinesVisible( 1, false );

    splineRenderer.setSeriesVisibleInLegend( 1, Boolean.FALSE );

    splineRenderer.setBaseItemLabelsVisible(true);

    splineRenderer.setBaseItemLabelGenerator(new StandardXYItemLabelGenerator());

    splineRenderer.setSeriesStroke(

        0, new BasicStroke(

            1.0f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND,

            1.0f, null, 0.0f

        )

    );

    //splineRenderer.setSeriesPaint(0, new Color(0, 1, 165 ));

    splineRenderer.setSeriesPaint( 0, new Color( 255, 140, 0 ) );

    xyPlot.setDataset( 1, xyPlot.getDataset(0) );

    XYItemRenderer defaultRenderer = new XYLineAndShapeRenderer();

    defaultRenderer.setSeriesVisible( 0, Boolean.FALSE );

    defaultRenderer.setSeriesVisibleInLegend( 0, Boolean.FALSE );

    xyPlot.setRenderer( 1, defaultRenderer );

    xyPlot.setRenderer( 0, splineRenderer );

  }

}

Thanks in advance

Hi,

Try this one:

HTH,

XYDataset xyDataset = xyPlot.getDataset();if(xyDataset != null){  for(int i = 0; i < xyDataset.getSeriesCount(); i++)  {	  splineRenderer.getSeriesShape(i).getBounds().setSize(your_width, your_height);			  }}

 I had a similar need.  I had better luck using renderer.lookupSeriesShape(0), since the Shape returned by renderer.getSeriesShape(0) can be null.
