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

Here's the updated answer from jjoe64, with the x-values obtained from Date#getTime()

    final DateFormat dateTimeFormatter = DateFormat.getDateTimeInstance();        
    graphView = new LineGraphView(context, "Chart");
    graphView.setCustomLabelFormatter(new CustomLabelFormatter() 
    {
        @Override
        public String formatLabel(double value, boolean isValueX) 
        {
            if (isValueX)
            {
                return dateTimeFormatter.format(new Date((long) value));
            }
            return null; // let graphview generate Y-axis label for us
        }
    });
