Thanks, your answer inspired me. The solution that works is this:
************
>From the controller file:
points=[[point.thedate.strftime('%Y-%m-%d'), point.value] for point in
pointlist]
************
>From the view file:
<script>
<!--
jQuery(document).ready(function() {
var p = {{=XML(response.json(points))}}
$.jqplot('chart1', [p], {
title:'Default Date Axis',
axes:{xaxis:{renderer:$.jqplot.DateAxisRenderer}},
series:[{lineWidth:4, markerOptions:{style:'square'}}]
});
});
-->
</script>
<div id="chart1" style="margin-top:20px;margin-left:20px; width:200px;
height:200px;">
</div>
