Author: ybbqy BLOG Welcome to visit ybbqy of: http: Story made rules //blog.9cbs.net/ybbqy: Today's theme is drawing on the page! Page picture? The HTTP browsing of the text is very hanging? In fact, there are many related technologies on the Internet, and I will use VML here. (Note: VML is currently only supported by IE6.0, and Microsoft will not intend to support VML, here is only throwing bricks, and believes that serious readers will do it. I want to be practical, compatible, suggestion, still generate on server Picture or use Java.applet. Under my trial, IE5.0 does not support the relative coordinates of the container, all coordinates begin from the top right corner of the web, and also advise them here.) Think: First we draw a coordinate, The mapping of coordinates I have not used VML itself, because the calculation of the loss will make the speed slowly. The actual coordinate width of the coordinates is 600, which is 200 pixels, the logical width is determined by the number of data, and the logic is determined by maximum data. The proportional factor is the actual number of pixels. We know a logical pixel that multiply the proportional factor can get the corresponding actual pixel coordinates. On this basis, we use JavaScript control to draw the needed line chart. First, you must use the Dongdong you want to use, I don't know what, I heard that I can check the information, I can check the information. HTML XMLns: V = "URN: Schemas-Microsoft-COM: VML">
