    Hi All,

    Hopefully others may find an answer to this useful as well! I'm trying to create what is essentially a scatter plot with multiple series, labels etc. A bit like this:

    The main tools I have access to are SAS 9.1, Excel 2007, Processing (although I'd rather not have to code something up from scratch). What would be the best way to tackle this? If it ends up being "Processing" then I'll code up a tool to do it and publish it (if one doesn't already exist) but that'll take me a while!

    Many thanks for any pointers.

    Andy.

    out of those three, i'd go with processing. You might want to check out ggplot in R. I don't specific examples, unfortunately, but I feel like I've seen something like that before.

    Thanks Nathan - I have R as well but didn't think of plotting in that. I'll check out the ggplot routine.

    Cheers,

    Andy.

    I've had a quick look at the R ggplot function but also found this:

    http://www.yeroon.net/ggplot2/

    A web implementation of the ggplot2. It can connect to a local data file or a Google Docs spreadsheet and gives you a lot of freedom in creating the image. Managed to get this out of it, which is pretty close:

    Cheers,

    Andy

    great. i should've mentioned that too. you can then export that as a PDF and then make edits in Adobe Illustrator or the open source version of it.

    I don't know what your final output needs to be (web/static) but I do this very thing with Flex/Flash (even if Steve Jobs would prefer I didn't...) for use on the web. The extra bonus is that I can animate the motion rather than simply drawing the line. If done correctly it's quite a bit more expressive. (if done incorrectly it's just annoying).

    Unfortunately I can't provide a link (internal product) but could cobble together a basic version if there's interest.

    So, web-only, and the tool is not on your list (nor is it free...) but thought I'd throw it out there.

    Thanks for that PR - I've come across a couple of other visualisation tools not in the public domain that use Flex. I've now actually learned "Processing" to produce a different visualisation so I'm going to use that to create this one as well. Should be able to animate as well.

    Cheers,

    Andy.
