Generating statistics data to a web page
Laurent Duperval
I've been immersed in Javaland for so long that I'd forgotten the
simple joys of writing in Tcl. I've been asked by my employer to
produce a series statistics with graphs for one of our applications.
I've been using Tcl to get the data from the database and generate a
CSV file to import into Excel. I then use Excel to produce graphs
which show daily results and trends. As I'm doing this, I realise that
there is probably an easier way to do this. Specifically, I'd like to
not use Excel anymore. I'd like to produce the same graphs as GIF's or
whatever and then dump the data on a Web page. I'd set up the script
to run in a crontab every day or every week.
Now, I know I can get the data, I can do the sums and the means and
averages and all that kind of stuff. But the part that bugs me the
most is the graphs. So here are my questions:
- What can I use to produce the graphs for my statistics? I know about
BLT, what others are there? Since I'm on Unix, I'm not averse to using
external programs if needed.
- What do you use for statistical stuff in Tcl? Currently, I do a SQL
query, put the results in an array and then do calculations on the
array. For the time being, I only have about 250,000 rows to deal
with. My array has 8 indices so I'm dealing with about 2M entries in
the array. So far, Tcl is coping well but I'm afraid that as data
accumulates, my script will slow down tremendously and I may
eventually run out of memory (every time I run it, it extracts all
data from the database. I'm not sure I can get around that).
Thanks for all pointers.

gdtclft works pretty well. libgd is quite common.

David's already answered the how-to-graph part. Understand,
there's a distinction between BLT, Excel, and such, which
generally make pictures to be seen by a local user, and gd
and friends, which are more like command-line utilities for
production of image files in various formats. For your situ-
ation, you want the latter.
You might want to read *Perl Graphics Programming* for back-
ground. I think you'll find it interesting.
Perl and Python both have more polished answers to the
questions you're asking. And, of course, there's R <URL:
http:/wiki.tcl.tk/r >; maybe you can get it to work with Tcl.
That should be nice. Have you already looked through <URL:
http://wiki.tcl.tk/statistics >?

^^^^^^^^^^^^^^^^^^^
Whoops. Some of that stuff is seriously out of date. Have a look at
http://CRAN.R-project.org/doc/Rnews/
Specifically, papers by me in vol 1/3, and (important) updates in vol
2/3.
What we currently have is a Tcl interpreter embedded in R and
interface routines and (some) object reflection and communication
mechanisms, which allow you to run Tcl stuff from within R.
What we don't have is the reverse: Mechanisms that let you control R
from Tcl. Well, we do have some rudiments of it, but not as elaborate
as in the other direction. In principle R is embeddable; you can build
R as a shared object and link it into another program, but you
probably need to jump through a few hoops to get event loops and such
stuff right. (I believe http://developer.r-project.org/embedded.html
is the best documentation we have.)

Right. I mentioned BLT because it was the only grahphing package I knew
about.

I haven't actually. There's some interesting stuff there. I'll take a look
at the various options to see which might be best suited for me. If not,
maybe this will give me a good enough reason to finally give Python a
spin.
Thanks!

There's even the simple yet very effective method of stretching
tables using simple html.
You might be able to use gnuplot. It uses the gd library.
David Bigelow
I have often been frustrated by the old stand-bys.
One thing I am using and seems to work well - is a PURE TCL/TK
solution that I wrote for one of my applications.
I created a standard canvas and then plotted on it what I needed -
line and bar graphs are all that I am currently worried about. The
only trick is that you must compensate for the -Y Axis to move the
start corner of your plots from the upper left corner to the lower
left corner. - then compensate for the scale factor / size of the
canvas. Those are the toughest parts!
I then use Img to export the canvas to GIF. Then I pump that to the
http request using a CGI.
if [catch {image create photo -format window -data .c} ph] {
# tk_messageBox -message "ERROR: Cannot create photo from canvas
window!\n\n$ph"
error
}
if {"[string toupper [file extension $filename]]" != ".GIF"} {
set filename "$filename.GIF"
catch {file delete -force $filename}
}
# Write the GIF Image of the Canvas
$ph write "../images/$filename" -format "GIF"
You will probably take a slight performance hit due to the
non-opimized code (e.g., native C/C++ for the graphing) but the ONLY
Problem I have found is that the canvas MUST be visible when you are
exporting it to GIF. While a "focus -force ." seems to solve this -
this method appears to require the apoplication to be visible. Also,
other tk/non-tk application windows will CLIP the image for some
reason. I would love to have this NOT be the case, but I have no idea
how to fix it.
If anyone knows how to generate GIF images using the canvas and Img
WITHOUT actually having to have a canvas visible on the desk top -
please let me know!
Hope this helps.

I'm looking at this option and the Dataplot option. I think my approach
will be to grok data using Tcl, generate the input needed by the *plot
programs and let them do their magic. I just need to figure out how to
tell the plotting functions to draw the correct curves.
This newsgroup is invaluable.

arrays of binary data (referred to as a matrix). Think of it is
a MatLab-like Tcl extension. Provies arithmetic operations on
matrices, transformations, various data types, ability to read and
write binary data in little or big endian byte order, ability
to write image file formats with or without automatic compression,
plot drawing (with PLplot), and various other image manipulation
procedures.

Description: Tcl/Tk/C++/C spreadsheet developed for Linux.
Supports graphics, printing, saving and loading different formats,
cell editing, sorting, column and row manipulation, cell formats,
undo/redo, formulas, and more.
Team also references a tool called Abacus for the Palm Pilot,
however I don't believe it has any Tcl/Tk connection.

For those following along at home, Rohan's "stretching tables"
