使用来自ASP.net中.CSV文件的数据实时显示图表

Question

i am trying to display a real time graph using the data coming from different csv files, i need to take the data from the latest csv file and display it.I am new to ASP and i am using MVC3.

This is my controller code for graph:

            string[] _yval = ReadFile2ArrayFromChannel3();
            var bytes = new Chart(width: 1600, height: 100)
            .AddSeries(
            chartType: "Line", legend: "Abc", xField: "t", yFields: "mv",
                // xValue: _xval,
             yValues: _yval)
            .GetBytes("png");
            return File(bytes, "image/png");

ReadFile2ArrayFromChannel3() function is taking the data from a csv file. I want to know how to change the values in runtime, since this graph controller is only being called once when i click on the action link from my ASP page. Thanks in advance.

If you want to display a real time chart, you are using the wrong approach. My I suggest you look into something like Telerik Chart or Highchart
