Wijmo 更优美的jQuery UI部件集：复合图表(CompositeChart)

Wijmo的CompositeChart控件允许您使用一个Chart来分析和展现复杂的数据。相同的数据可以使用不同的可视化效果，不同的图表类型展现在一个图表内，使得用户可以从不同的角度，了解分析这组数据所表达的内容 。

本文将介绍如何使用Wijmo的CompositeChart控件，制作一个复合图表。CompositeChart 的API：http://wijmo.com/wiki/index.php/Compositechart，Wijmo 的CompositeChart 化繁为简，将传统 Excel like图表中的三大区域: Plot Area, Legend Area, Label Area, 分离成为更为简单的API: SeriesList, Legend, Axis, Hint, 使得开发者更加容易的理解和使用。

Wijmo的CompositeChart 依赖于下面的这5个核心的JavaScript库:

raphael.js

globalize.min.js

jquery.ui.widget.js

jquery.wijmo.raphael.js

jquery.wijmo.wijchartcore.js

如果需要加入别的类型的Chart，需要再引入其它Chart类型的JavaScript库，这样可以使得开发者可以灵活定制并裁剪出适合自己用例的JavaScript库。例如本实例使用了 PieChart, BarChart, LineChart, 引入的JavaScript库如下：

jquery-1.7.1.min.js

jquery-ui-1.8.18.custom.min.js

globalize.min.js

raphael-min.js

jquery.wijmo.raphael.js

jquery.wijmo.wijchartcore.js

jquery.wijmo.wijbarchart.js

jquery.wijmo.wijpiechart.js

jquery.wijmo.wijlinechart.js

jquery.wijmo.wijcompositechart.js

写点代码，设置一下Chart :

$(document).ready(function () {

$("#wijcompositechart").wijcompositechart({

axis: {

y: {

text: "Total Hardware"

},

x: {

text: ""

}

},

stacked: false,

hint: {

content: function () {

return this.label + '\n ' + this.y + '';

}

},

header: {

text: "Hardware Distribution"

},

seriesList: [{

type: "column",

label: "West",

legendEntry: true,

data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [5, 3, 4, 7, 2] }

}, {

type: "column",

label: "Central",

legendEntry: true,

data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [2, 2, 3, 2, 1] }

}, {

type: "column",

label: "East",

legendEntry: true,

data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [3, 4, 4, 2, 5] }

}, {

type: "pie",

label: "asdfdsfdsf",

legendEntry: true,

center: { x: 150, y: 150 },

radius: 60,

data: [{

label: "MacBook Pro",

legendEntry: true,

data: 46.78,

offset: 15

}, {

label: "iMac",

legendEntry: true,

data: 23.18,

offset: 0

}, {

label: "MacBook",

legendEntry: true,

data: 20.25,

offset: 0

}]

}, {

type: "line",

label: "Steam1",

legendEntry: true,

data: {

x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],

y: [3, 6, 2, 9, 5]

},

markers: {

visible: true,

type: "circle"

}

}, {

type: "line",

label: "Steam2",

legendEntry: true,

data: {

x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],

y: [1, 3, 4, 7, 2]

},

markers: {

visible: true,

type: "tri"

}

}

]

});

});

代码不多，就有了下图的效果:

代码不多，很好分析：

--

axis: {

y: {

text: "Total Hardware"

},

x: {

text: ""

}

--

设置X，Y 轴。

---

stacked: false

---

设置Bar 为非stacked.

---

hint: {

content: function () {

return this.label + '\n ' + this.y + '';

}

},

---

设置鼠标 Tooltip.

---

header: {

text: "Hardware Distribution"

},

---

设置图表头.

----

seriesList: [{

type: "column",

label: "West",

legendEntry: true,

data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [5, 3, 4, 7, 2] }

}, {

type: "column",

label: "Central",

legendEntry: true,

data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [2, 2, 3, 2, 1] }

}, {

type: "column",

label: "East",

legendEntry: true,

data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [3, 4, 4, 2, 5] }

}, {

type: "pie",

label: "asdfdsfdsf",

legendEntry: true,

center: { x: 150, y: 150 },

radius: 60,

data: [{

label: "MacBook Pro",

legendEntry: true,

data: 46.78,

offset: 15

}, {

label: "iMac",

legendEntry: true,

data: 23.18,

offset: 0

}, {

label: "MacBook",

legendEntry: true,

data: 20.25,

offset: 0

}]

}, {

type: "line",

label: "Steam1",

legendEntry: true,

data: {

x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],

y: [3, 6, 2, 9, 5]

},

markers: {

visible: true,

type: "circle"

}

}, {

type: "line",

label: "Steam2",

legendEntry: true,

data: {

x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],

y: [1, 3, 4, 7, 2]

},

markers: {

visible: true,

type: "tri"

}

}

]

----

设置 SeriesList，每个Series 可以设置其type, label, legendEntry, data, 等等属性。 Series可以设置 SeriesStyles, 和 SeriesHoverStyles, 如:

seriesStyles: [{

fill: "#8ede43", stroke: "#7fc73c", opacity: 0.8

}],

seriesHoverStyles: [{

"stroke-width": "1.5", opacity: 1

}]

经过上面的设置，这个CompositeChart就设置好了。也可以使用Server返回的 Json 数据动态绑定生成Chart。
