  • Summary I: Scientific graphing

    Sorry to take so long, but here is a collation of the replies I received
    after posting the
    following request:
    On June 21, I posted the following:

    Our lab would be interested in others experience with Windows-based
    scientific graphing programs (e.g. SigmaPlot, Stanford Graphics, Axum,
    PSI-Plot, etc). We have been using PSI-Plot (DOS) with a good deal of
    success -- except for a couple of quirks. We are looking to enhance our
    capabilities and would be interested in others opinions of graphing programs
    on the market.

    Hi Jane,

    I've been using Kaleidagraph for the Mac for several years now despite the
    fact that 99% of my data are generated via PC applications. The
    Kaleidagraph program takes full advantage of the Mac environment and is
    fully compatible with various other Mac applications including Word. I've
    had a great deal of success with creating a graph in Kaleidagraph and
    pasting it into a word document on the Mac and later bringing up the
    document and graph on the PC.

    I've also had experience with SigmaPlot on the PC and it's OK, only OK.
    I've just ordered CorelDraw for the PC and hope it lives up to it's promise.
    So far it seems to me to be a great deal more difficult to use then the
    Kaleidagraph software but I'm committed to it (at least short term! ;^) )

    Oh yeah, there's always Excel! Almost forgot an honorable mention for
    SPSS/windows. It has excellent plotting capabilities including 3-D but
    falls short when you want to incorporate the plots into other applications.

    hope this helps!



    I have two suggestions for your graphics programs:
    a) Powerpoint (the best I have ever seen for just graphics)
    b) The Graphics that are included within Wordperfect for Windows 6.0a are
    also exceptional.
    c) Harvard Graphics (I am not quit sure if they came out with the Windows
    version yet but the DOS version is also quite good).
    I hope I helped you a little bit,

    I have been using SigmaPlot for many years and have used many versions from the
    early DOS versions through to the current version (2 for Windows).

    I have found it to be very good and use it a lot. The only major
    exception was the first version for Windows which had more bugs than
    you could count...but they quickly advised that a new version was coming to
    fix the bugs and it was provided for free (better than Microsoft!).

    It is very easy to use and very intuitive so that you don't need
    to read the manuals to begin with; you can just start working
    with data and producing graphs.Contact me if you have more specific
    questions that I might be able to answer.

    I have extensive experience with SigmaPlot, having used various versions for
    6 years. I appreciate its strengths and acknowledge its weaknesses. At
    various times I have researched the other programs with similar capabilities
    and have found no reason to change although some of them may offer something
    slightly different or better.

    Graph wise, you want to do it you can do it
    Reading in data, in general, is a snap
    Customer service is friendly and helpful even if they say that you can't
    do it
    Multiple graphs per page, multiple plots per graph, many x and y axes
    Multiple graph alignment can be done visually or numerically
    Integrates with Word although depending on your computer it can be slow
    Does grid lines

    The price of power is a very steep learning curve
    Spreadsheet capabilities tend to be a number of versions behind what you
    expect (Excel)
    Cannot automate repetitive tasks (no internal macro language, nor can
    Visual Basic be used externally)
    When you have many graphs on a sheet the redraw really slows down
    Rarely get customer support immediately (have to wait for them to call back)
    Can't create headers or footers
    Can't create multiple graph pages from a spreadsheet
    There's a bug when drawing and saving reference lines that hasn't been
    corrected in maintenance updates and can't combine horizontal and vertical
    reference lines. (Can draw a line manually)
    No spacing tool
    As far as I can tell, can't do gray scale fills

    If you have specific questions please feel free to contact me.

    Try Harvard Graphics and SYSTAT (DOS) as well. The former is good for
    making presentation slides. The latter produces nice plots and is reasonably
    diverse in statistical capabilities.
    I look forward to the summary of responses!

    In graduate school, I used Axum (DOS version) for graphical representation of
    data. I highly recommend it. It is completely menu driven and easy to learn.

    The main features I liked were:
    1) Spreadsheet capabilities (many graphing programs offer limited data
    manipulation commands).
    2) The ability to save graph setup "templates". If you are making a large
    number of graphs of the same type of data, you can save a "template" (complete
    with titles and axis labels) so you don't have to repeat the same graph
    commands for each new dataset.
    3) An interactive graphics mode where you can change titles, labels, etc
    while viewing the graph, as opposed to executing a menu command followed by
    the "show graph" key.
    4) For 3-D graphing, Axum allows you to change the "viewpoint" of the
    graph to make the data easier to see. i.e., You can play with the
    rotation and azimuth angles until you get the best view of your data.
    5) Related to #2, if you have a lot of data files that require the same
    manipulation and graphing setup, you can create a type of batch file that
    you input from DOS that will automatically execute all of the Axum commands
    required and show the graph. It saves a LOT of time.

    Hope this is helpful.
