How would I add a vertical line to the plot. It should stretch from the top to bottom of the plot. I tried the following to see if I could see the line, but it does not show up.

tuningLine = new ChartShape (pTransform1,
new Line2D.Double(1, 5, 500, 505),
ChartShape.NORM_PLOT_POS, 2, 2, ChartShape.NORM_PLOT_POS, 0);
ChartAttribute tuneLineAtt = new ChartAttribute(Color.green,
5,ChartConstants.LS_SOLID, Color.green);
tuneLineAtt.setFillFlag(true);
tuningLine.setChartObjAttributes(tuneLineAtt);
gWG.addChartObject(tuningLine);

From the our example program scatterplots.LabeledDatapoints

Line2D titleLine = new Line2D.Double(0.1,0.1, 0.9,0.1);

ChartShape titleLineShape = new ChartShape(pTransform1, titleLine,
ChartConstants.NORM_GRAPH_POS, 0.0, 0.0, ChartConstants.NORM_GRAPH_POS,0);
titleLineShape.setLineWidth(3);
gWG.addChartObject(titleLineShape);

I would guess that you seem to be using device (java user coordinates) instead of normalized (0.0 - 1.0) plot coordinates, which is what you specifying with ChartConstants.NORM_GRAPH_POS.
