XyShapeRenderer - Remove outline stroke from legend (items)

[datobalu]

Hi,

I am having trouble with the Legend items of XYPlot. By default the legend items (which I made into circles) have grey outline strokes. I need to remove those strokes and fill the circles with native color. I tried accessing legend items through shapeRenderer.getLegendItem(), but I failed to reach my goal.

Here is my code (sorry for huge import list, I use them in later parts of the code).

Code: Select all

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.geom.Ellipse2D;
import java.awt.Polygon;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.Legend;
import org.jfree.chart.StandardLegend;
import org.jfree.chart.annotations.XYShapeAnnotation;
import org.jfree.chart.axis.NumberAxis;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.chart.plot.XYPlot;
import org.jfree.data.XYDataset;
import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RefineryUtilities;
import java.awt.Color;
import org.jfree.data.Range;
import org.jfree.chart.annotations.XYTextAnnotation;
import org.jfree.chart.renderer.xy.*;


double xMax = chart.getXYPlot().getDomainAxis().getRange().getUpperBound();
double yMax = chart.getXYPlot().getRangeAxis().getRange().getUpperBound();
String[] cols = {"0x008542","0x019086","0x0190ee","0x0325A8","0x5506BA","0xAE07C5","0xD10994","0xE30D16","0xEF660F","0xF49B11"};

chart.getXYPlot().getDomainAxis().setRange(0.00,xMax);

XYShapeRenderer shapeRenderer = new XYShapeRenderer();
shapeRenderer.setBaseShape(new Ellipse2D.Double(1,1,7,7),false);	//circles for data-points
shapeRenderer.setBaseLegendShape(new Ellipse2D.Double(1,1,7,7));	//circles for Legend

int datacount = chart.getPlot().getDataset().getSeriesCount();
int colidx;
Color tmp;
////////////////////////////

	for (int i = 0; i < datacount; i++) 
	{ 
		if(datacount <= cols.length) {
			colidx = i * (int) (cols.length / datacount);
		} else {
			colidx = i % cols.length;
		}
		tmp = Color.decode(cols[colidx]);
		shapeRenderer.setSeriesPaint(i, new Color(tmp.getRed(),tmp.getGreen(),tmp.getBlue(),160)); //last component is alpha-transparency (for overlapping points)
	}

//LAST STEP!
chart.getXYPlot().setRenderer(shapeRenderer);
 
	/* //dotRenderer
	XYDotRenderer dotRenderer = new XYDotRenderer();
	dotRenderer.setDotHeight(7);
	dotRenderer.setDotWidth(7);
    dotRenderer.setSeriesPaint(0, Color.red);
    dotRenderer.setSeriesPaint(1, Color.green);
    dotRenderer.setSeriesPaint(2, Color.orange);
    dotRenderer.setSeriesPaint(3, Color.blue);
	dotRenderer.setLegendShape(new Ellipse2D.Double(1,1,7,7));
	chart.getXYPlot().setRenderer(dotRenderer);	*/

One solution would be to call setSeriesOutlinePaint(seriesIndex, new Color(0, 0, 0, 0)) which will make the outline transparent.

Thank you David. It Worked!
This was the best present for my birthday today.

Great! Happy birthday
