mvc 生成chart

只需要1步

View 注意红色部分

@{

var chart = new Chart(width:450,height:300)
  .AddTitle("数据分析")
  .AddTitle(name:"X",xValue:new[]{"2","3","4"})
  .AddTitle(name:"Y",yValue:new[]{"2","3","4"})
  .Save("~/Content/Images/tem.png");
}

<image src="../Content/Images/tem.png" />

 

 

用Action类似

var imageStream = new MemoryStream();

var chart = new Chart(width:450,height:300)
  .AddTitle("数据分析")
  .AddTitle(name:"X",xValue:new[]{"2","3","4"})
  .AddTitle(name:"Y",yValue:new[]{"2","3","4"})

  .Save("~/Content/Images/tem.png");

retrun FIleStream(imageStream ,"../Content/Images/tem.png");

对应的view

<image src="../Content/Images/tem.png" />
