Question

I am trying to add the error bars over the datapoints in a scatter plot using XYErrorRenderer. The dataset used is XYDataset. The code I have used for it is:

XYErrorRenderer rendererPoints = new XYErrorRenderer();
rendererPoints.setShapesVisible(true);
rendererPoints.setDrawXError(false);
rendererPoints.setDrawYError(true);
rendererPoints.setCapLength(new Double(0.2));

rendererPoints.setShapesFilled(true);
rendererPoints.setLinesVisible(false);

I want to add the error bars vertically, but it is not working for me. Please help.
