jqPlot DateAxis tickInterval not working

I found a solution! You need to specify the tickinterval as a javascript timestamp. So lets say you want 1 hour. That would be 1000*60*60 = 3600000 (javascript timestamps are in milliseconds).

So you would write: tickInterval:'3600000',

Works here.

tickInterval:'1 day' works. You can try:

xaxis: {
        renderer: $.jqplot.DateAxisRenderer,
        rendererOptions: { tickRenderer: $.jqplot.CanvasAxisTickRenderer },
        tickOptions: { formatString: '%b' },
        tickInterval: '1 day'
       }

Since I think you cannot answer your own question (and I ran in to the same problem), i'll post your solution as answer, as it solved it on my side too:

Providing a min attribute for the axis does appear to fix this (for whatever reason... bug?), so unless anyone has any better ideas I'll do this!
