jquery flot和周数 [英] Jquery flot and week numbers

问题描述

我制作了一个页面，按周数绘制平均降雪量。现在我们进入了2010年，第1周我的图形在x轴（年周）上延伸了间隔。
我想要的是x轴上的周数（51,52,1,2等）和固定的间隔宽度。
任何人都知道如何做到这一点？

I made a page to plot average snowdepth by week number. Now that we entered 2010, week 1 my graph stretches the interval on the x-axis (yearweek). What I want is the weeknumber on the x-axis (51,52,1,2 etc), and a fixed intervalwidth. Anyone know how to do that?

示例

<script id="source" language="javascript" type="text/javascript">
$(function () {

var d1 = [
[201001,118],[200952,112],[200951,102],[200950,97],[200949,93],
[200948,41],[200947,10],[200947,0]];

var d2 = [
[201001,33],[200952,31],[200951,31],[200950,25],[200949,23],
[200948,12],[200947,0],[200947,0]];

$.plot($("#placeholder"),
   [{data:d1,lines:{show: true},
     points:{show: true},label:"Mountain"},
    {data:d2,lines:{show: true},points:{show: true},label:"Valley"}],
    {xaxis: {tickSize:1, tickDecimals:0 }}
);

});
</script>

推荐答案

您可以定义一组'ticks' x轴，并映射你的星期数量在那里

you could define a set of 'ticks' for the x-axis, and map your week numbers there

{xaxis: 
    {
        ticks: [[201001,'1'],[200952,'52'],[200951,'51'],....]
        tickSize:1, 
        tickDecimals:0
    }
}

- V2似乎有效，请参阅 flot chart

<div id="placeholder" style="width:600px;height:300px;"></div> 
<script id="source" language="javascript" type="text/javascript">
$(function () {

var d1 = [
[200952,112],[200951,102],[200950,97],[200949,93],[200948,41],[200947,10],[200946,0]];

var d2 = [
[200952,31],[200951,31],[200950,25],[200949,23],[200948,12],[200947,0],[200946,0]];

$.plot($("#placeholder"),
   [{data:d1,lines:{show: true},
     points:{show: true},label:"Mountain"},
    {data:d2,lines:{show: true},points:{show: true},label:"Valley"}],
    {xaxis: {
        ticks: [[200952,'52'],[200951,'51'],[200950,'50'],[200949,'49'],[200948,'48'],[200947,'47'],[200946,'46']],
        tickSize:1, tickDecimals:1 }}
);

});
</script>

看起来'200947'在您的数据集中是两次。

It seems '200947' is in your data set twice.
