我试图把一个JSON文件到NVD3条形图,但我不能做我想做的。我不知道很多JS的,但努力学习的最终项目在学校,所以请大家帮忙=]NVD3离散BARCHART使用JSON
继承人我从一个例子得到了代码:
<!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>
我的问题是在这里:
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值放在那里,我该怎么做?
这是我的JSON文件,一个如果对于X,和其它用于Y轴:
X轴:
{ “periodos”:[ “112”, “121”,“122 “ ”131“, ”132“, ”141“]}
Y轴:
{ ”reprovados“:[ ”247“, ”164“, ”250“, ”147“,” 144 ”,‘0’]}
如果有人能请你回答我尽可能完整,我会非常感激=]
内periodos值应在X上的描述,和值内reprovados钢筋尺寸,这是这样做是错误的很好,只是名称。我怎样才能把周期值放在X轴上?顺便说一句,谢谢很多人!你是个天才hahahah –
现在我完全理解了......更新了演示...... thx恭维 – rafaelcastrocouto
Thansk,现在完美了哈哈我怎样才能从文件传递json值,而不是写在变量上呢? ! –
