Contour Plot in web browser

I need to plot a contour chart in the web browser开发者_如何学JAVA. It needs to be interactive as well. Does anyone know good javascript library, flash or flex libary to do this?

I'm a Flex developer so I can speak to that section of this question at least. From what I've seen this doesn't exist in Flash/Flex (at least in any open available source) and to a large degree this question is too vague to answer, perhaps link to some example images of what it is you're trying to create. From doing a Google search of contour chart images I see there's quite a variety of implementations based on different usages. In general though within Flex there's a datavisualization framework that includes some starting points for doing charting if you're interested in checking that out a bit more here's the link: http://livedocs.adobe.com/flex/3/html/help.html?content=Part7_DataVis_1.html

Alternatively you could start bit more "from scratch" and use Degrafa as the starting point: http://livedocs.adobe.com/flex/3/html/help.html?content=Part7_DataVis_1.html

Or just go all the way and do it for real from scratch using the flash drawing primitives, if you have a clear understanding of your goal and the chart isn't expected to be re-used in lots of varying scenarios you may be best off going this route as you'll have the tightest control over the end product. I did this for building a pseudo 3D bar chart and it was actually easier than expected, I haven't yet but I'll post the code along with some other charts I've made at http://www.shaunhusain.com/charts (need to reboot to linux to get that example, will post within the next 4 hours).
