        xyPlot.setDrawingCacheEnabled(true);
        int width = xyPlot.getWidth();
        int height = xyPlot.getHeight();
        xyPlot.measure(width, height);
        Bitmap bmp = Bitmap.createBitmap(xyPlot.getDrawingCache());
        xyPlot.setDrawingCacheEnabled(false);
        FileOutputStream fos = new FileOutputStream(fullFileName, true);
        bmp.compress(CompressFormat.JPEG, 100, fos);
