jqplot text labels on y-axis GANTT like chart
===

I'm trying to make a GANT like chart in jqplot. I want to make two timelines in the same plot. As you can see by the code, I've got this working for the most part.

I've added a few series manually (and added a series config) ofcourse this will be in a loop later.

The problem I have now is that on the Y-axis I don't want numbers, but the text labels of the series ("contact" and "Locatie"). It would be nice if this is done dynamically, but 'hardcoding' them is not a problem since I only need two at the moment.

I can't find an example that does this. Any ideas?
here's the jsFiddle: http://jsfiddle.net/NVbjv/1/


        var seriesCnf = Array();
        var loc = Array();

        // add location values
        loc.push([[1340877534000, 1, 'lagehaghorst'] , [1340877569000, 1, 'lagehaghorst' ]]);
        seriesCnf.push({color: "#941B80", label: "Locatie"});
        loc.push([[1340877779000, 1, 'weegnet'] , [1340877869000, 1, 'weegnet' ]]);
        seriesCnf.push({color: "#941B80"});
        loc.push([[1340877989000, 1, 'lagehaghorst'] , [1340878139000, 1, 'lagehaghorst' ]]);
        seriesCnf.push({color: "#941B80"});

        // add ignition values
        loc.push([[1340877534000, 2, 'uit'], [1340877561000, 2, null]]);
        seriesCnf.push({color: "#FF0000", showMarker:false, label: "Contact"});
        loc.push([[1340877561000, 2, 'aan'], [1340877779000, 2, null]]);
        seriesCnf.push({color: "#00FF00", showMarker:false, pointLabels: {location: 'n'}});
        loc.push([[1340877779000, 2, 'uit'], [1340877839000, 2, null]]);
        seriesCnf.push({color: "#FF0000", showMarker:false});
        loc.push([[1340877839000, 2, 'aan'], [1340878019000, 2, null]]);
        seriesCnf.push({color: "#00FF00", showMarker:false, pointLabels: {location: 'n'}});
        loc.push([[1340878019000, 2, 'uit'], [1340878139000, 2, null]]);
        seriesCnf.push({color: "#FF0000", showMarker:false});

        plot1 = $.jqplot('container', loc,{
            seriesColors: ["#941B80"],
            title: "Tijdlijn",
            axes: {
              xaxis: {
                renderer: $.jqplot.DateAxisRenderer,

                    tickOptions: {

                        angle: 0
                    },
              },
              yaxis: {
                min: 0,
                tickInterval: 1,
              }
            },
            seriesDefaults: {
                showMarker:true,
                pointLabels:{
                    show:true,
                    location:'s',
                    labelsFromSeries: true,
                    formatter: $.jqplot.DefaultTickFormatter,
                }
            },
            series: seriesCnf,

            grid: {
                background: '#ffffff'
            }
        });
