Xaxis date overlapped

[xiaolei1998]

hello!

I am using the date plot and trying to display the date on x axis, but the date is overlapped, I don't know how to modify this.

    LineGraphSeries<DataPoint> series = new LineGraphSeries<>(arrayDataPoints);
    series.setDrawDataPoints(true);

    plot.addSeries(series);

    plot.getGridLabelRenderer().setLabelFormatter(new DateAsXAxisLabelFormatter(DisplayExpTimePlot.this));
    plot.getGridLabelRenderer().setNumHorizontalLabels(plotValue.size()-1);

    plot.getViewport().setXAxisBoundsManual(true);
    plot.getGridLabelRenderer().setHumanRounding(false);

    GridLabelRenderer glr = plot.getGridLabelRenderer();
    glr.setPadding(52);

looking forward for your reply.
