Graphing in PSPP

[hippie dream]

From what I understand, PSPP does have graphing capabilities. I just installed the program but I am sure how to graph.  I installed libplot in the hope of graphing. The only answer an internet search gave me was that graphing should be available. My question: Should you be able to graph in the GUI, and if so does this mean I am missing some components of the package or is graphing only command-line based? Thanks!

[John Darrington]

There are a number of operations which produce graphs:

EXAMINE has a /PLOT subcommand which produces various kinds of graph.
FREQUENCIES has /HISTOGRAM and /PIECHART subcommands.

Currently the gui doesn't have the ability to display graphs.
Using the postscript driver, graphs are embedded in the output.
Using the text output driver, graphs are written to seperate PNG files.

So is there no way to actually modify the graphs then? I can produce them using the text output driver but then they appear as PNG files as you said. At that point I can't really change the axes or titles or really do anything. I'm getting the feeling that graphing in PSPP is a work in progress. Don't get me wrong, I understand that it isn't a simple task to accomplish.

Also, I don't really know what postscript drivers are. Sorry. Enlighten me? Thanks for your help!

That's right. Ben has an idea for making an output engine that would
let us make nicer graphics, but coding that hasn't begun yet.

PSPP's primary purpose is statistical analysis.  If you're looking for
a general purpose plotting/data visualisation  program I suggest that
you try gnuplot.
     
     Also, I don't really know what postscript drivers are. Sorry. Enlighten me?

See section A.6 of the manual.

  Well, I am very noob using statistical analysis, but at university, we
use SPSS, and we always have to generate both tables and graphics, so I
had got the feeling about graphics are a key tool for statistical
analysis... Off course, I don't complain about lacking the edit graphics
feature, as long as it is in the "to do" list...

     analysis...

I agree.  An important part of statistical analysis is the ability to
represent data in a way that assists visualisation, and graphs are one
obvious way to do that.   But I get the feeling that "hippie dream" is
interested in generating plots with fancy fonts, 3D effects etc (for
which gnuplot is ideal), rather than to understand a trend in some
data.   Of course it's always possible to use PSPP to transform your
data into a form which can be used by gnuplot (or some other plotting
tool).

      Off course, I don't complain about lacking the edit graphics
     feature, as long as it is in the "to do" list...

Yes.  It's on the list.   If you feel like helping out, post a message
to the pspp-dev mailing list.

  Unfortunately, I have problems making a simple calculator with visual
basic, so I think the only help I can provide, is dressing as a
cheerleader, and since I am a guy, I think it would not help much... but
I will try to make some friend, both of them users of spss, to try pspp,
and provide some feedback, if you think that may be useful...

Burn! I am definitely not looking for fancy 3D graph but I am looking for graphs that are publishable quality and that can be manipulated easily after I produce them. Fancy font?!! C'mon. All I was saying is that the program in good but simply preliminary and doesn't cover my graphing needs yet. Really, I do thank you for your help though.

Well I think that PSPP satisfies the first criterion, but not yet the
second. Hopefully this feature will be addressed in the next release.

     I do thank you for your help though.

You're welcome.

By the way, I am not clear about how to make graphics with pspp.... I was expecting to find a submenu under Analyze - Explore.... but there is nothing graphic related there...

Currently there is no way to ask for graphs through the GUI's dialog
boxes.  You can make graphs with FREQUENCIES and EXAMINE, which you
can find in the 'Analyze' dropdown menu in the GUI. But to make these
procedures produce graphs, you must type keywords to the syntax
generated by the dialog box. You can do this by using the dialog box
to select whatever summaries you want, then pressing the 'Paste'
button in the dialog box, then adding whatever graphing subcommand you
need (e.g. /HISTOGRAM or /PLOT).

I found that the easiest way to get started is to build relationship you are dealing using EXPLORE or DESCRIPTIVES then paste into a syntax window then add the PLOT or BOXPLOT or whatever command and go from there. By building then pasting you bypass all the other syntax required. Hope that helps.
