我想使用 Google Chart Interactive 与 ASP.NET 和 C# 创建图表我发现了这个示例 http://code.google.com/apis/ Visualization/documentation/using_overview.html 但我发现问题如何将其与 C# 集成以及如何将数据从 C# 集成到 JavaScript。有人可以提示我应该做什么吗？

您需要做的是将命令发送到 google Charts api 并将响应转换为如下所示的图像，然后您可以获取图像对象并将其写入文件或执行您想要的任何操作：

 string ChartURL = "http://chart.apis.google.com/chart?";
            ChartURL += "chxr=0,0," + MaxX + "";
            ChartURL += "&chxt=y";
            ChartURL += "&chbh=a";
            ChartURL += "&chs=" + ChartWidth + "x" + ChartHeight + "";
            ChartURL += "&cht=bvg";
            ChartURL += "&chco=" + ChartColors + "";
            ChartURL += "&chds=" + ChartDataRange + "";
            ChartURL += "&chd=t:" + ChartValues + "";
            ChartURL += "&chdl=" + ChartLegend + "";
            ChartURL += "&chtt=" + ChartTitle + "";

            HttpWebRequest myRequest = WebRequest.Create(ChartURL) as HttpWebRequest;
            HttpWebResponse ServerResponse = myRequest.GetResponse() as HttpWebResponse;
            Stream ResponseStream = myRequest.GetResponse().GetResponseStream();
            return System.Drawing.Image.FromStream(ResponseStream);

What you need to do is send the command to the google charts api and convert the response to an image like below, and then you can take the image object and write it to a file or perform any operation you want:

 string ChartURL = "http://chart.apis.google.com/chart?";
            ChartURL += "chxr=0,0," + MaxX + "";
            ChartURL += "&chxt=y";
            ChartURL += "&chbh=a";
            ChartURL += "&chs=" + ChartWidth + "x" + ChartHeight + "";
            ChartURL += "&cht=bvg";
            ChartURL += "&chco=" + ChartColors + "";
            ChartURL += "&chds=" + ChartDataRange + "";
            ChartURL += "&chd=t:" + ChartValues + "";
            ChartURL += "&chdl=" + ChartLegend + "";
            ChartURL += "&chtt=" + ChartTitle + "";

            HttpWebRequest myRequest = WebRequest.Create(ChartURL) as HttpWebRequest;
            HttpWebResponse ServerResponse = myRequest.GetResponse() as HttpWebResponse;
            Stream ResponseStream = myRequest.GetResponse().GetResponseStream();
            return System.Drawing.Image.FromStream(ResponseStream);
