Inconsistent behavior with date series

[nicolabeghin]

Hi everyone
I'm very pleased with the library, great works!

Problem is, I don't understand why it behaves inconsistently, meaning that one time it shows like this (without date X labels and incorrect Y axis rounding)

in place of the correct display

I'm following the example Dates.java
https://github.com/jjoe64/GraphView-Demos/blob/master/app/src/main/java/com/jjoe64/graphview_demos/examples/Dates.java

if (story.getId().equals(storyId)) {
    GraphView graph = (GraphView) findViewById(R.id.graph);
    DataPoint[] dataPoints = new DataPoint[story.getMetrics().size()];
    int i = 0;
    for (Story.Metric metric : story.getMetrics()) {
        dataPoints[i] = new DataPoint(metric.getDate(), (int)metric.getConversations());
        i++;
    }
    LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(dataPoints);
    series.setAnimated(true);
    graph.addSeries(series);
    graph.getGridLabelRenderer().setLabelFormatter(new DateAsXAxisLabelFormatter(graph.getContext(), new SimpleDateFormat(LABEL_DATE_FORMAT)));
    graph.getGridLabelRenderer().setNumHorizontalLabels(dataPoints.length);
    // as we use dates as labels, the human rounding to nice readable numbers
    // is not nessecary
    graph.getGridLabelRenderer().setHumanRounding(false);

    // set manual x bounds to have nice steps
    graph.getViewport().setMinX(story.getMetrics().get(0).getDate().getTime());
    graph.getViewport().setMaxX(story.getMetrics().get(story.getMetrics().size() - 1).getDate().getTime());
    graph.getViewport().setXAxisBoundsManual(true);

}

I'm really puzzled..

thanks

Same goes to me but my date redundance.

` DateFormat fmt1 = new SimpleDateFormat("MMMM dd, yyyy", Locale.US);
Date d1 = null,d2 = null,d3 = null,d4 = null,d5 = null,d6 = null,d7 = null,
d8 = null,d9 = null,d10 = null,d11 = null, d12 = null;

    try {
        d1 = fmt1.parse("January 1,  2018");
        d2 = fmt1.parse("February 1,  2018");
        d3 = fmt1.parse("March 1,  2018");
        d4 = fmt1.parse("April 1,  2018");
        d5 = fmt1.parse("May 1,  2018");
        d6 = fmt1.parse("June 1,  2018");
        d7 = fmt1.parse("July 1,  2018");
        d8 = fmt1.parse("August 1,  2018");
        d9 = fmt1.parse("September 1,  2018");
        d10 = fmt1.parse("October 1,  2018");
        d11 = fmt1.parse("November 1,  2018");
        d12 = fmt1.parse("December 1,  2018");
    } catch (ParseException e) {
        e.printStackTrace();
    }

    graphView = (GraphView)v.findViewById(R.id.graph);

    series = new LineGraphSeries<>(new DataPoint[] {
            new DataPoint(d1, 0),
            new DataPoint(d2, 123.00),
            new DataPoint(d3, 200.00),
            new DataPoint(d4, 145.00),
            new DataPoint(d5, 150.00),
            new DataPoint(d6, 180.00),
            new DataPoint(d7, 0.00),
            new DataPoint(d8, 0.00),
            new DataPoint(d9, 0.00),
            new DataPoint(d10, 0.00),
            new DataPoint(d11, 30.00),
            new DataPoint(d12, 0.00)
    });
    series.setColor(ContextCompat.getColor(getActivity(), R.color.bgwhite));

    //series.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.bgwhite));
    graphView.addSeries(series);

    // set date label formatter
    DateFormat fmt = new SimpleDateFormat("MMM", Locale.US);
    graphView.getGridLabelRenderer().setLabelFormatter(new DateAsXAxisLabelFormatter(getActivity(), fmt));
    graphView.getGridLabelRenderer().setNumHorizontalLabels(12); // only 4 because of the space
    graphView.getGridLabelRenderer().setTextSize(20f);
    graphView.getGridLabelRenderer().setLabelHorizontalHeight(10);

    // set manual x bounds to have nice steps
    graphView.getViewport().setMinX(d1.getTime());
    graphView.getViewport().setMaxX(d12.getTime());

    graphView.getViewport().setXAxisBoundsManual(true);
    //graphView.getViewport().calcCompleteRange();

    // as we use dates as labels, the human rounding to nice readable numbers

// is not necessary
graphView.getGridLabelRenderer().setHumanRounding(false); // show line graph y`
