# EChartsGen
在后端使用ECharts库，将ECharts图表Png图像文件导出到本地磁盘
## 快速开始
1. 在项目中引用[EChartsGen]( https://www.nuget.org/packages/EChartsGen)
```
dotnet add package EChartsGen
```
2. 指定一个option用于生成Echarts
> option是一个json对象，用于配置图表的各个属性，从而定义图表的展示形式。详情请查看官网：https://echarts.apache.org/zh/option.html
```
Exporter exporter = new Exporter();
var pngPath = await exporter.ExportAsync(new EChartsGen.ExportOption() { ChartOptionPath = "D:/option.json", OutputPath="D:/out" });
```
或使用Option对象参数
```
Exporter exporter = new Exporter();
var title = "血压监测结果分析"; var passCount = 40; var failedCount = 2;
var pngPath = exporter.ExportAsync(new EChartsGen.ExportOption()
{
Height = 400,
Width = 580,
ChartOption = new ChartOption()
{
title = new List()
{
new Title (){
text=title, left="center"}
},
tooltip = new ToolTip(),
legend = new Legend()
{
orient = OrientType.vertical,
left = "left"
},
series = new object[]
{
new {
name= "Access From",
type="pie",
data=new object[]
{
new { value= failedCount, name="异常" },
new { value= passCount, name="正常" },
}
}
}
},
OutputPath="D:/out"
})
```
查看结果：
## ExportOption 说明
* ChartOptionPath - Option的json文件路径
* ChartOption - Option的.Net对象
* Height - 图片高度
* Width - 图片宽度
* OutputPath - 图片文件的生成目录,若为空则默认生成至工作目录下`\libs\phantomjs-2.1.1-windows\tmp`
ChartOptionPath和ChartOption二选一，如果同时指定，优先使用ChartOptionPath。
图片的高度和宽度默认为1920*800，你可以根据实际情况调整。
## 示例
1. 运行单元测试
2. 使用文档模板生成工具将ECharts图形填充到Word文档示例，请前往[EChartsGen_DocTemplateTool_Sample](./EChartsGen_DocTemplateTool_Sample/)
