我試圖把一個JSON文件到NVD3條形圖,但我不能做我想做的。我不知道很多JS的,但努力學習的最終項目在學校,所以請大家幫忙=]NVD3離散BARCHART使用JSON
繼承人我從一個例子得到了代碼:
<!DOCTYPE html> <meta charset="utf-8">
<link href="../src/nv.d3.css" rel="stylesheet" type="text/css">
<style>
body { overflow-y:scroll; }
text { font: 12px sans-serif; }
svg { display: block; }
#chart1 svg{ height: 500px; min-width: 100px; min-height: 100px; /* margin: 10px; Minimum height and width is a good idea to prevent negative SVG dimensions... For example width should be =< margin.left + margin.right + 1, of course 1 pixel for the entire chart would not be very useful, BUT should not have errors
*/ }
</style> <body>
<div id="chart1">
<svg></svg> </div>
<script src="../lib/d3.v3.js"></script> <script src="../nv.d3.js"></script> <!-- including all the components so I don't have to minify every time I test in development --> <script src="../src/tooltip.js"></script> <script src="../src/utils.js"></script> <script src="../src/models/axis.js"></script> <script src="../src/models/discreteBar.js"></script> <script src="../src/models/discreteBarChart.js"></script> <script>
historicalBarChart = [ {
key: "Cumulative Return",
values: [
{
"label" : "A" ,
"value" : 29.765957771107
} ,
{
"label" : "B" ,
"value" : 0
} ,
{
"label" : "C" ,
"value" : 32.807804682612
} ,
{
"label" : "D" ,
"value" : 196.45946739256
} ,
{
"label" : "E" ,
"value" : 0.19434030906893
} ,
{
"label" : "F" ,
"value" : 98.079782601442
} ,
{
"label" : "G" ,
"value" : 13.925743130903
} ,
{
"label" : "H" ,
"value" : 5.1387322875705
}
] } ];
nv.addGraph(function() { var chart = nv.models.discreteBarChart()
.x(function(d) { return d.label })
.y(function(d) { return d.value })
.staggerLabels(true)
//.staggerLabels(historicalBarChart[0].values.length > 8)
.tooltips(false)
.showValues(true)
.transitionDuration(250)
;
d3.select('#chart1 svg')
.datum(historicalBarChart)
.call(chart);
nv.utils.windowResize(chart.update);
return chart; });
</script>
我的問題是在這裏:
historicalBarChart = [
{
key: "Cumulative Return",
values: [
{
"label" : "A" ,
"value" : 29.765957771107
} ,
{
"label" : "B" ,
"value" : 0
} ,
{
"label" : "C" ,
"value" : 32.807804682612
} ,
{
"label" : "D" ,
"value" : 196.45946739256
} ,
{
"label" : "E" ,
"value" : 0.19434030906893
} ,
{
"label" : "F" ,
"value" : 98.079782601442
} ,
{
"label" : "G" ,
"value" : 13.925743130903
} ,
{
"label" : "H" ,
"value" : 5.1387322875705
}
]
}
];
我想把我的Json值放在那裏,我該怎麼做?
這是我的JSON文件,一個如果對於X,和其它用於Y軸:
X軸:
{ 「periodos」:[ 「112」, 「121」,「122 「 」131「, 」132「, 」141「]}
Y軸:
{ 」reprovados「:[ 」247「, 」164「, 」250「, 」147「,」 144 」,‘0’]}
如果有人能請你回答我儘可能完整,我會非常感激=]
內periodos值應在X上的描述,和值內reprovados鋼筋尺寸,這是這樣做是錯誤的很好,只是名稱。我怎樣才能把週期值放在X軸上?順便說一句,謝謝很多人!你是個天才hahahah –
現在我完全理解了......更新了演示...... thx恭維 – rafaelcastrocouto
Thansk,現在完美了哈哈我怎樣才能從文件傳遞json值,而不是寫在變量上呢? ! –
