绘图图 [英] Drawing Graphs

问题描述

大家好，

任何人都可以建议在网页上显示交互式图形的最佳方法是什么.我想要一个线性图和一个控制该图上垂直线的滑块.因此，这个想法是，每当滑块移动时，垂直线便沿着图形移动，并且无论垂直线与线性图相交的位置，都应该有一个标签以文本形式显示x值和y值.

通过从文件中读取x和y坐标来绘制线性图.

我可以使用纯ASP.NET吗?还是因为它是交互式图形显示，所以使用Silverlight会更好吗?也许，已经有现成的API可以执行这种功能了吗?

我非常感谢任何建议.

预先谢谢您.

Hi all,

Can anyone advise what is the best way to display interactive graphs on a web page. I would like to have a linear graph and a slider that controls a vertical line on the graph. So, the idea is whenever the slider is moved the vertical line moves along the graph and there should be a label showing the x-value and y-value in text form, wherever the vertical line intersects with the linear graph.

The linear graph is drawn by reading x and y co-ordinates from a file.

Can I use plain ASP.NET? Or would it be better to use Silverlight since it is interactive graphical display? Perhaps, there is an off-the-shelf API that does this funtionality already?

I would very much appreciate any advice.

Thank you in advance

推荐答案

在asp.net 4.0中有一些内置的Chart控件. 斯科特·格思里 [使用Ajax增强图表 [ silverlight工具包 [图表控件 [ ^ ]

There are some built in Chart controls in asp.net 4.0. Scott Guthrie[^] has a blog post with lots of info on getting started.

They aren''t really "interactive" out of the box though. You will have to get you hands a bit dirty with some javascript/ajax to manipulate them. 4GuysFromRolla have an article on Enhancing Charts With Ajax[^] (also linked from Scott''s blog) which should get you started.

If you''d rather go down the silverlight route, take a look at the silverlight toolkit[^] which includes some charting controls[^]
