private void save_jpg()
//pScale  - method that draw's the grafic on the jpanel
pScale(datanal(tabel.getRowCount(),col_1,coloane_selectate.get(coloanele.nextElement())),pane);
BufferedImage myImage = new BufferedImage(pane.getWidth(),pane.getHeight(),BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = myImage.createGraphics();
pane.paint(g2);
     try {
         OutputStream out = new FileOutputStream("1grafic.jpg");
         JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
JPEGEncodeParam param =encoder.getDefaultJPEGEncodeParam(myImage);
          //the first parameter here is the "quality v file size" trade-off
          //play with this value (0-1) to determine the best results for you
          param.setQuality(0.9f, true);
          encoder.encode(myImage, param);
          out.flush();
          out.close();
       } catch (Exception ec) {
         System.out.println(ec);
       }
