本项目是一个.Net版的ECharts开发包,参考@abel1533的java版本,主要目的是方便在.NET中构件Echarts中可能用的全部数据结构,完整的Option结构. ChartOption中的数据Series,包含Line-折线图,Bar-柱状图,Pie-饼图,Scatter-散点图等,支持Echarts中所有图表.支持所有Style类,如AreaStyle,ItemStyle,LineStyle等.支持多种Data数据类型,一个通用的Data数据,以及PieData,PolarData,TreeData等个性化数据结构. 你可以使用本项目直接构件一个Option对象,使用方法JsonTools.ObjectToJson2(option),(直接使用Json方式返回存在问题,因为function不是标准化的json格式,转换会报错).
图表类型
• Line - 折线（面积）图
• Bar - 柱状（条形）图
• Scatter - 散点（气泡）图
• K - K线图
• Pie - 饼（圆环）图
• Radar - 雷达（面积）图
• Chord - 和弦图
• Force - 力导向布局图
• Map - 地图
• Gauge - 仪表盘
• Funnel - 漏斗图
• Heatmap - 热力图
• EventRiver - 事件河流图
• Venn - 韦恩图
• Tree - 树图
• Treemap - 矩形树图
• WordCloud - 词云
Echarts组件
• Axis - 坐标轴
• Grid - 网格
• Title - 标题
• Tooltip - 提示
• Legend - 图例
• DataZoom - 数据区域缩放
• DataRange - 值域漫游
• Toolbox - 工具箱
• Timeline - 时间线

ChartOption说明
-
ChartOption 是echarts的主要类. -
使用JsonTools.ObjectToJson2方法返回给前端时,需要使用eval('(' + data + ')')转换为JSON结构.
Function说明
由于json标准中不包含function类型,一般json库都不支持这种类型,处理这种类型最简单的方式是转换json字符串时,对字符串进行处理. 读者可以自行使用其他自定义方式实现,本项目使用的.net自带的JRaw()方式.不管是:
"formatter": function(params) {
// for text color
var color = colorList[params[0].dataIndex];
var res = '<div style="color:' + color + '">';
res += '<strong>' + params[0].name + '消费（元）</strong>'
for (var i = 0, l = params.length; i < l; i++) {
res += '<br/>' + params[i].seriesName + ' : ' + params[i].value
}
res += '</div>';
return res;
},和
"color": (function (){
var zrColor = require('zrender/tool/color');
return zrColor.getLinearGradient(
0, 400, 0, 300,
[[0, 'green'],[1, 'yellow']]
)
})(),都可以利用JRaw来实现.
option.ToolTip().Trigger(TriggerType.axis)
.BackgroundColor("rgba(255,255,255,0.7)")
.Formatter(new JRaw(@"function(params) {
// for text color
var color = colorList[params[0].dataIndex];
var res = '<div style=""color:' + color + '"">';
res += '<strong>' + params[0].name + '消费（元）</strong>'
for (var i = 0, l = params.length; i < l; i++) {
res += '<br/>' + params[i].seriesName + ' : ' + params[i].value
}
res += '</div>';
return res;
}"))和
style.Emphasis().BarBorderColor("green").BarBorderWidth(5)
.Color(new JRaw(@"(function (){
var zrColor = require('zrender/tool/color');
return zrColor.getLinearGradient(
0, 400, 0, 300,
[[0, 'red'],[1, 'orange']]
)
})()"))
本项目通过ASP.NET MVC和ASP.NET web api模拟了echarts官网网站中的全部示例,主要目的是方便大家参考使用和调整结构.
