脚本功能在Chrome中运行一次，但在Firefox中可以正常运行

Question

I am using NVD3 to make several graphs. I put a console.log in the addGraph function which adds a particular graph.

I am wondering whether there is something wrong in my code? Am I using the library correctly? I do not know where to begin to resolve this issue.

CODE

Calling the scripts

<script src="../../../data/novus/lib/d3.v2.js"></script>
<script src="../../../data/novus/nv.d3.js"></script>
<script src="../../../data/novus/src/tooltip.js"></script>
<script src="../../../data/novus/src/models/legend.js"></script>
<script src="../../../data/novus/src/models/axis.js"></script>
<script src="../../../data/novus/src/models/scatter.js"></script>
<script src="../../../data/novus/src/models/line.js"></script>
<script src="../../../data/novus/src/models/multiChart.js"></script>

In the loop

<script src="../../../data/novus/nv.d3.js"></script>
<script>
    var impressions = [];
    var clickrate = [];
    var trial_impressions = [];
    var trial_clickrate = [];
    var testdata = [{
        "key" : "Impressions",
        "type" : "line",
        "values" : impressions,
        "yAxis" : 1
    }, {
        "key" : "Clicks",
        "type" : "line",
        "values" : clickrate,
        "yAxis" : 2
    }, {
        "key" : "T Impressions",
        "type" : "line",
        "values" : trial_impressions,
        "yAxis" : 1
    }, {
        "key" : "T Clicks",
        "type" : "line",
        "values" : trial_clickrate,
        "yAxis" : 2
    }].map(function(series) {
        series.values = series.values.map(function(d) {
            return {
                x : d[0],
                y : d[1]
            }
        });
        return series;
    });
    var chart;

    nv.addGraph(function() {
        console.log("Add");
        chart = nv.models.multiChart().margin({
            top : 30,
            right : 60,
            bottom : 50,
            left : 70
        }).x(function(d, i) {
            return i
        }).color(d3.scale.category10().range());

        chart.xAxis.tickFormat(function(d) {
            var dx = testdata[0].values[d] && testdata[0].values[d].x || 0;
            if ( typeof (dx) == undefined || d > 1000) {
                dx = new Date(d);
            } else {
                dx = new Date(dx);
            }
            return dx ? d3.time.format('%x')(dx) : '';
        });

        chart.yAxis1.tickFormat(d3.format(',.1f'));
        v

        chart.yAxis2.tickFormat(d3.format(',.4f'));

        d3.select('#chart1<?= $chartID?> svg').datum(testdata).transition().duration(500).call(chart);
        return chart;
    });

</script>

The div where the graph is called

<div id='chart1<?= $chartID?>' style="width:1110px;height:300px;font-size:11px;margin-top:5px">
    <svg></svg>
</div>

My best guess is that there is mathematical calculations on those numbers. In witch case using the function parseFloat() can convert the string to a number so that mathematical calculations will be done correctly.
