The plot(s) on this page use the following plugin:

<script type="text/javascript" src="../plugins/jqplot.dateAxisRenderer.min.js"></script>

Date axes support is provided through the dateAxisRenderer plugin. Date axes expand javascripts native date handling capabilities. This allow dates to be input in almost any unambiguous form, not just in milliseconds!

line1=[['2008-09-30',4], ['2008-10-30',6.5], ['2008-11-30',5.7], ['2008-12-30',9], ['2009-01-30',8.2]];
plot9 = $.jqplot('chart1', [line1], {
    title:'Default Date Axis',
    axes:{xaxis:{renderer:$.jqplot.DateAxisRenderer}},
    series:[{lineWidth:4, markerOptions:{style:'square'}}]
});

Date Axes also provide powerful formatting features. This allows custom formatter strings to be used to format axis tick labels precisely the way you want.

            tickOptions:{formatString:'%b %#d, %y'},
            min:'May 30, 2008', 
            tickInterval:'1 month'
        }
    },
