我是这些东西的新手。使用来自URL:http://jsfiddle.net/sujay/UMeGS/的代码,我试图用我自己的数据创建一个图表。
使用REST Web服务,我可以从数据库中获取数据,这意味着当我点击以下链接' localhos:48095/WebApplication22/webresources/sample22.test15
' ,我得到如下的json数据
[
{
"id": 1,
"status": "stopped",
"unit": "a",
"val": 24
},
{
"id": 2,
"status": "working",
"unit": "a",
"val": 59
},
{
"id": 3,
"status": "turning",
"unit": "a",
"val": 2
},
{
"id": 5,
"status": "transport",
"unit": "a",
"val": 6
},
{
"id": 6,
"status": "stopped",
"unit": "b",
"val": 336
},
{
"id": 7,
"status": "working",
"unit": "b",
"val": 212
},
{
"id": 9,
"status": "turning",
"unit": "b",
"val": 23
},
{
"id": 10,
"status": "transport",
"unit": "b",
"val": 1
}
]
我稍微修改了http://jsfiddle.net/sujay/UMeGS/的代码,其中我使用了getJSON()来获取数据。
以下是代码。
$(function () {
$.getJSON('localhos:48095/WebApplication22/webresources/sample22.test15', function (data) {
var seriesData = [];
var xCategories = [];
var i, cat;
for (i = 0; i < data.length; i++) {
cat = 'Unit ' + data[i].unit;
if (xCategories.indexOf(cat) === -1) {
xCategories[xCategories.length] = cat;
}
}
for (i = 0; i < data.length; i++) {
if (seriesData) {
var currSeries = seriesData.filter(function (seriesObject) {
return seriesObject.name == data[i].status;
});
if (currSeries.length === 0) {
seriesData[seriesData.length] = currSeries = {
name: data[i].status,
data: []
};
} else {
currSeries = currSeries[0];
}
var index = currSeries.data.length;
currSeries.data[index] = data[i].val;
} else {
seriesData[0] = {
name: data[i].status,
data: [data[i].val]
}
}
}
var chart;
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: xCategories
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -100,
verticalAlign: 'top',
y: 20,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
formatter: function () {
return '<b>' + this.x + '</b><br/>' + this.series.name + ': ' + this.y + '<br/>' +
'Total: ' + this.point.stackTotal;
}
},
plotOptions: {
column: {
stacking: 'normal'
}
},
series: seriesData
});
});
});
});
但我无法看到任何东西。图表不显示。请帮帮我。
