Point2D p = chartPanel.translateScreenToJava2D(mouseChartEvent.getTrigger().getPoint());
Rectangle2D plotArea = chartPanel.getScreenDataArea();
XYPlot plot = (XYPlot) chart.getPlot(); // your plot
double chartX = plot.getDomainAxis().java2DToValue(p.getX(), plotArea, plot.getDomainAxisEdge());
double chartY = plot.getRangeAxis().java2DToValue(p.getY(), plotArea, plot.getRangeAxisEdge());
