Item value display problem

flembo · Post by **flembo** » Fri Nov 19, 2004 8:32 am

I have a chartapplet drawing both bars and lines. I'm using a XYBarRenderer for the bars and a StandardXYItemRenderer for the lines. I want to to display ItemLabels and to do this I use the following code:

Code: Select all

renderer.setLabelGenerator(new StandardXYLabelGenerator());
renderer.setItemLabelsVisible(true);

It works perfectly with the lines but I can't make it work with the bars!

Why not???

In your code you set the labels only for one renderer. Because you are using two renderer you have forgotten this for the second?

No I'm using the posted code for both renderes! The following method is invoked from a While loop:

Code: Select all

public AbstractXYItemRenderer createRenderer(){
  AbstractXYItemRenderer r;
  if(getKurveType().equals("bar")){
    r = new XYBarRenderer(0.20000000000000001D);
  }
  else {
    r = new StandardXYItemRenderer();
    ((StandardXYItemRenderer)r).setPlotShapes(true);
  }
  r.setToolTipGenerator(new StandardXYToolTipGenerator("{0}: ({1}, {2})", new SimpleDateFormat("d-MMM-yyyy"), new DecimalFormat("0.00")));						 
  r.setLabelGenerator(new StandardXYLabelGenerator()); 
  r.setItemLabelsVisible(true);
		
  return r;
}

There is nothing wrong with the code. It compiles and runs perfectly, the setItemLabelsVisible(boolean) method is implemented in the AbstractRenderer. The XYBarRenderer extends the AbstractXYItemRenderer which again extends the AbstractRenderer so the method is provided
