Color of point and legend not the same

I'm dealing with a pie chart with a legend describing the individual data 

points. The chart is holding 5 data points and I'm using the default palette. 

Because the colors of point 1 and point 5 are very similar (blue: the latter is 

a little brighter) I'd like to set the color of point 5 manually using the 

following line of code :

this.getPoint(0,4).setColor(Color.PINK); // pink as an example

Additionally I'm setting the chart to display the legend with the following:

this.setLegendBox(true);

this.getLegendBoxObj().setDocked(Docked.BOTTOM);

The result is a nicely formatted pie chart, where the slice number 5 is colored 

in pink, but the corresponding legend marker (filled rectangle) is showing only 

a pink border instead of being completely pink.

To exemplify, I've attached the generated chart.

 From the documentation I understood that the legend item should have the same 

color than the point marker. Am I missing something?

Any help appreciated,

	Kurt

Thank you for your help, but this didn't solve the problem. I'm getting the same 

result. The slice of the pie is colored in pink, but the marker in the legend is 

only showing a pink border and the default color fill.

It's exactly the same than using the code mentioned before:

this.getPoint(0,4).setColor(Color.PINK) //only one series

Any clues?

I have tried the following code:

Chart chart1 = new Chart();

chart1.setGallery(Gallery.PIE);

chart1.setChart3D(true);

chart1.openData(COD.VALUES, 1, 3);

chart1.getValue().setItem(0, 0, 20);

chart1.getValue().setItem(0, 1, 45);

chart1.getValue().setItem(0, 2, 30);

chart1.closeData(COD.VALUES);

chart1.setPointLabels(true);

chart1.getPoint(1).setColor(java.awt.Color.PINK);

chart1.setLegendBox(true);

chart1.getLegendBoxObj().setDocked(Docked.BOTTOM);

which produced the attahced image.  Can you post a fragment of code that 

reproduces the problem?

Thanks,

GA

Thank you for your help. Let me provide you with some code fragments taken from 

my sources.

My chart is defined by a class as the following snipplet explains:

public class WellBeing extends GenericChart {

public WellBeing(Location location) throws KeyNotFoundException{

  super(location);

  InputStream is = ChartUtil.getConfigInputStream(this);

  try {

  	this.importChart(FileFormat.XML, is);

  } catch (IOException e) {

  	log.error("Couldn't read WellBeing config.",e);

  }

  data = getSomeValue();

  if (data!=null){

  	ChartUtil.populate(this, data);

  	adjustChart();

  }

}

private void adjustChart() {

  this.getPoint(4).setColor(Color.PINK);

  //some other adjustments ...

  this.setLegendBox(true);

  this.getLegendBoxObj().setDocked(Docked.BOTTOM);

}

The class GenericChart extends SoftwareFX.ChartFX.Chart. Instantiating the class 

WellBeing exporting as a PNG file will show a chart where the slice (#4) is 

colored pink but the marker for the corresponding point shows only a pink border 

and is filled with the default color as exemplified in my initial post.

I do understand that I'm using inheritance, hence the WellBeing chart will 

inherit attributes from GenericChart, but I'm setting the color directly in the 

class and therefore should overwrite any previous settings (if any).

That is the way it works.  When you set the scheme to GRADIENT that means 

that the points are doing to be painted with a gradient from the point color 

to the point alternate color.  Since you were changing only the color and 

the the alternate color was still the default, you were getting a gradient 

from Pink to Blue, and that's what the legend showed.  Since the Pie was 3D 

it was difficult to see, try with a 2D and you you will see exactly what I 

mean.
