Using dates with the Graphview library

Question

I\'m using GraphView library (see: https://github.com/jjoe64/GraphView or http://www.jjoe64.com/p/graphview-library.html)

But I would like to use Date/Time for the X

Answer 1

I created the horizontal labels at the same time I was setting the values:

public void initializeLineGraphView() {

    // Get last weeks entries from the DB
    ArrayList entries = DbManager.getInstance().getLastWeeksEntries(new Date());
    String[] hLabels = new String[entries.size()];
    GraphView.GraphViewData[] graphViewData = new GraphView.GraphViewData[entries.size()];

    for(int i = 0; i < entries.size(); i++) {

        Entry entry = entries.get(i);
        int pain = entry.getPain();
        graphViewData[i] = new GraphView.GraphViewData(i, pain);

        // Generate the horizontal labels
        SimpleDateFormat sdf = new SimpleDateFormat("EEE");
        String dayOfWeek = sdf.format(entry.getDate());
        hLabels[i] = dayOfWeek;

    }

    mSeries = new GraphViewSeries("", null, graphViewData);
    GraphView graphView = new LineGraphView(getActivity(), "");
    graphView.addSeries(mSeries);
    graphView.setHorizontalLabels(hLabels);
    graphView.setVerticalLabels(new String[] {"10", "5", "0"});
    mLineGraphView = graphView;

}
