Question

我已经尝试过使用jquery更新protovis，但没有任何反应。这是我的代码。

<script type="text/javascript+protovis">
var minnesota =  [{name:"job 1", values:[182904,196530,203944,192492,77393,81243]}]

$(document).ready(function(){
draw();
$("button").click(function(){
minnesota = [{name:"changed job", values:[342,34234,2342,543]}]
draw();
});

});



    function draw(){
    var w = 200,
        h = 30,
        numberFormat = pv.Format.number(),
        dateFormat = pv.Format.date("%B %Y");

    /* Color by maximum number of people employed in that job. */
    var c = pv.Scale.log(minnesota, function(d) pv.max(d.values))
        .range("#ccc", "#1f77b4");

    /* Tile the visualization for each job. */
    var vis = new pv.Panel()
        .data(minnesota)
        .width(w)
        .height(h + 10)
        .top(6)
        .left(6)
        .right(6)
        .bottom(6);

    /* A panel instance to store scales (x, y) and the mouseover index (i). */
    var panel = vis.add(pv.Panel)
        .def("i", -1)
        .def("x", function(d) pv.Scale.linear(d.values, pv.index).range(0, w))
        .def("y", function(d) pv.Scale.linear(0, pv.max(d.values)).range(0, h))
        .bottom(10)
        .events("all")
        .event("mousemove", pv.Behavior.point(Infinity).collapse("y"));

    /* The area. */
    panel.add(pv.Area)
        .data(function(d) d.values)
        .fillStyle(function(d, p) panel.i() < 0 ? c(pv.max(p.values)) : "#2ca02c")
        .left(function() panel.x()(this.index))
        .height(function(d) panel.y()(d))
        .bottom(0)
        .event("point", function() panel.i(this.index))
        .event("unpoint", function() panel.i(-1));

    /* The x-axis. */
    panel.add(pv.Rule)
        .bottom(0);

    /* The mouseover dot. */
    panel.add(pv.Dot)
        .visible(function() panel.i() >= 0)
        .left(function() panel.x()(panel.i()))
        .bottom(function(d) panel.y()(d.values[panel.i()]))
        .fillStyle("#ff7f0e")
        .strokeStyle(null)
        .size(10);

    /* The label: either the job name, or the month and value. */
    panel.add(pv.Label)
        .bottom(-1)
        .textBaseline("top")
        .left(function() panel.i() < 0 ? 0 : null)
        .right(function() panel.i() < 0 ? null : 0)
        .textAlign(function() panel.i() < 0 ? "left" : "right")
        .textStyle(function() panel.i() < 0 ? "#999" : "#000")
        .text(function(d) panel.i() < 0 ? d.name
            : dateFormat(new Date(2000, panel.i() * 3, 1))
            + ": " + numberFormat(d.values[panel.i()]));

    vis.render();
    }
        </script>

当文件准备好然后它创建图表但是当我点击按钮然后它不重新绘制图表。我用firebug检查了新数据值，这很好，但它没有更新图表值。我已经尝试了很多寻找解决方案，但未能成功。任何伎俩？
