我正在尝试将jquery ajax调用中的一些数据加载到nvD3图表中。如果我不包含ajax调用,那么图表工作得很好,但如果我在调用ajax之后尝试加载数据,则根本不加载..
<script>
angular.module('app', ['onsen'])
nv.addGraph(function() {
var chart = nv.models.discreteBarChart()
.x(function(d) { return d.label }) //Specify the data accessors.
.y(function(d) { return d.value })
.staggerLabels(true) //Too many bars and not enough room? Try staggering labels.
.tooltips(false) //Don't show tooltips
.showValues(true) //...instead, show the bar value right on top of each bar.
;
d3.select('#chart svg')
.datum(exampleData())
.call(chart);
nv.utils.windowResize(chart.update);
return chart;
});
//Each bar represents a single discrete quantity.
function exampleData() {
$.ajax({
type: "GET",
url: "https://demo8162910.mockable.io/json",
dataType: 'jsonp',
jsonp: true,
jsonpCallback: "myJsonMethod",
error: function(){
console.log( 'Unable to load feed, Incorrect path or invalid feed' );
},
success: function(data){
console.log( 'feed done' );
return [
{
key: "Cumulative Return",
values: [
{
"label" : "A Label" ,
"value" : -29.765957771107
} ,
{
"label" : "B Label" ,
"value" : 0
} ,
{
"label" : "C Label" ,
"value" : 32.807804682612
} ,
{
"label" : "D Label" ,
"value" : 196.45946739256
} ,
{
"label" : "E Label" ,
"value" : 0.19434030906893
} ,
{
"label" : "F Label" ,
"value" : -98.079782601442
} ,
{
"label" : "G Label" ,
"value" : -13.925743130903
} ,
{
"label" : "H Label" ,
"value" : -5.1387322875705
}
]
}
]
}});
}

答案 0 :(得分:1)
我认为你需要把
d3.select('#chart svg')
.datum(exampleData())
.call(chart);
在success
功能中,用数据本身替换exampleData()
。
