实时Grapgh与Ms Chart [英] Real Time Grapgh with Ms Chart

问题描述

我需要建立一个实时图表。虽然如果我们在MS Chart中使用Ajax实时特征，它会在指定[由我们提供]时间段后刷新图形图像。这将告诉用户图表每隔（比方说）10秒刷新一次。



用户是否可能永远不会知道图表是通过即时数据更新刷新的。

Hi,

I have requirement to build a real-time graph. although if we use Ajax real time feature in MS Chart it refresh the graph image after specified [provided by us] time period. which will tell users that the graph is refreshing every ( say )10 second.

Is it possible that user will never know the graph is refreshing with instantaneous data update.

Thnks

推荐答案

如果您的问题是通知用户图表刷新，您可以使用Ajax UpdateProgress控件。例如，每次图表刷新时都会显示一个动画加载图像。

If your question is to inform user that the chart is refreshing you can use an Ajax UpdateProgress control. Showing for example, an animated loading image each time the charts refreshs.

我想，可以使用Asp.net中的Signal R来完成。我问的是与推送技术有关，比如Facebook更新不断刷新我们的墙壁。



我当时从来没有实现同样的，我只是在有机会使用Signal R技术后意识到这一点。

谢谢

I suppose, it can be done using Signal R in Asp.net. What i was asking was related to Push technology like Facebook updates keep coming to our wall without refreshing the page.

Well I never implemented the same at that time, I just realized it after having a chance to work on Signal R technology.
