  • graphing program - summary of responses

    Dear List,

    Thank you all for replying to my inquiry about graphing programs. Below is
    the original posting and a summary of responses.

    I have mean data with +/- 1 SD and I am attempting to make a line graph and
    shade the +/- 1 SD as a shaded area in grey. I have spent many hours
    playing with Excel but it only allows for High-Low Lines which come out as
    vertical lines. Could anyone please recommend a graphing program which is
    capable of performing this function.

    Several people made excellent suggestions for manipulating Excel and Declan
    Reidy was kind enough to send a sample graph in Excel which provided a good
    clue to accomplish exactly what I was trying to do. First, the mean +/- 1
    SD data must be arranged with +1SD, mean, -1SD in columns A, B, and C
    respectively. Graph these as a “Stacked” Area Graph. Select the -1SD by
    right clicking on the bottom portion of the graph (it will probably be
    yellow as a default), select Format Data Series, and change its color to
    white. Select the Mean series (purple) and change its color to grey and do
    the same to the +1SD area (blue). If you decide to add another series of
    data to graph over top, Excel will automatically graph these data as
    another stacked area graph. By right clicking on the new data and
    selecting Chart Type, you can change this to a line graph. I am happy to
    send anyone a sample of an Excel graph to demonstrate this.

    These are the various programs that were recommended:

    Matlab (the overwhelming favorite)
    Microcal Origin 6.0 (Data Analysis and Technical Graphics Software)
    SigmaPlot http://www.spssscience.com/SigmaPlot/index.cfm
    ReportGenerator http://www.motion-labs.com/report.htm
    DeltaGraph Pro
    AXUM software package by Mathcad, Inc.
    Visual3D http://www.motion-labs.com/
    Statistica

    A few people also suggested making the graph in Excel and export it to a
    photo editor such as Canvas, PaintPro, Photoshop, PowerPoint, etc…. to fill
    in the lines yourself.

    Many thanks again to all who replied.

    Sincerely,

    Reed Ferber
