  <p>I am reading data from a database. Is it possible to sort it before?</p>
  
  <p>Edit:</p>
  
  <pre><code>    public void setupAndShowGraph() {
      GraphViewData graphViewData[] = new GraphViewData[DatabaseSQLiteHelper.percentage.size()];
      for (int index = 0; index &lt; DatabaseSQLiteHelper.percentage.size(); index++) {
  
          graphViewData[index] = new GraphViewData(DatabaseSQLiteHelper.date.get(index), Double.parseDouble("" + DatabaseSQLiteHelper.percentage.get(index)));
      }
      drugGraphSeries = new GraphViewSeries(graphViewData);
  
      GraphView lineGraphView = new LineGraphView(getActivity(), "");
  
      lineGraphView.getGraphViewStyle().setGridColor(getResources().getColor(R.color.golden_brown));
      lineGraphView.getGraphViewStyle().setHorizontalLabelsColor(getResources().getColor(R.color.golden_brown));
      lineGraphView.getGraphViewStyle().setVerticalLabelsColor(getResources().getColor(R.color.golden_brown));
      lineGraphView.getGraphViewStyle().setTextSize(15.0F);
      lineGraphView.setScrollable(true);
      lineGraphView.setScalable(true);
  
      ((LineGraphView) lineGraphView).setDrawBackground(true);
      lineGraphView.addSeries(drugGraphSeries);
  
      LinearLayout linearLayout = (LinearLayout) rootView.findViewById(R.id.graphView);
      linearLayout.addView(lineGraphView);
  
  }
  </code></pre>
  
  <p>I have added the setupAndShowGraph() method. You can see in the line below,</p>
  
  <pre><code>     graphViewData[index] = new GraphViewData(DatabaseSQLiteHelper.date.get(index), Double.parseDouble("" + DatabaseSQLiteHelper.percentage.get(index)));
  </code></pre>
  
  <p>I am fetching the data using the above line, what all to add so that I can get a sorted series.</p>
