I thought it was part of their strategy to separate
the wheat from the chaff. They didn't print a whole
lot of T-shirts! :-)

Well, it turns out you should use the variables VX and VY from the
dataset, then you get what is shown in the PDF file. The other variables
in the data .sav file seem to be unnecessary, as well as the macro .sav
file they offer. It's not mentioned anywhere. Quality control seems to
be on vacation.

Well, see, there you go! I have to admit iTools are *almost*
worth switching to just for Printing alone. I find it extraordinarily
difficult to write a program that can be (1) displayed in a window,
(2) sent directly to a PostScript file, and (3) sent directly to
a printer.

The first two requirements are a piece of cake. I've gotten
so good at that that even my draw widgets know how to do it.
I don't have to do anything special to get that kind of
functionality.

But printing is a pain in the ass, primarily because you
have to have all your colors loaded *before* you SET_PLOT to
the 8-bit PRINTER device, and who writes programs like that
these days!? I feel like I am taking a step back into the
1970's every time I do it.

And, of course, object graphics fonts are beautiful.
I wish (hint, hint) they would make them available to
the rest of us.

Perhaps you're right. Those of us in the Dinosaur Club
better get with it. :-)

Cheers,

David

Check your SPAM filter. That's where I found my notice.
And tutorial 2 is a bit odd. There is a SAVE file that
comes with it, but as far as I can see, it has nothing
to do with the tutorial. I had to make up my own data
(not hard in direct graphics).

Cheers,

David

I've been doing my tutorials religiously. There is a T-shirt
at stake, after all.

> If so, what do you think?

Well, I find I can do all kinds of things with a line
plot that I had never imagined I would want to do. I spent
three hours one day moving all the axes around, seeking
a more aesthetic arrangement, something that would speak
to the artist in me as well as the scientist. Finally,
I settled on the original box axes as the arrangement I liked
best (although that Picasso-like arrangement was nice),
but how would I have ever known without the opportunity
to try other arrangements?

I'm trying to be humorous (although God knows, with
a too much of a sarcastic wit).

To be serious for a moment, I *greatly* appreciate these
tutorials. The more I learn about iTools, the more I
appreciate them. A LOT of work and effort has gone into
them. Even an idiot like me can see that!

But, personally, I find them WAY too complex. I find I'm
not interested in 60-70 percent of what the tool allows
me to do. And when I *am* interested in a tool, I'd like
it to do something just a little bit different. I can't
make heads or tails of how to program the darn things
to get them to work my way, so they frustrate me. When
I get frustrated, I get sarcastic. Ask my wife. :-(

Anyway, I keep plugging away at the tutorials and enjoying
them immensely. I keep telling myself that sooner or later
I am going to see why a scientist will want to use these
rather than the good ol' direct graphics. :-)

Cheers,

David

After having discoverd no more than five percent of their features, I
find the iTools really useful for creating a quick plot where I can add
annotations, change axis ranges, arrange multiple images on a page etc.
easily. Also, very importantly, I can print with a mouseclick (and
adjust the size on the paper interactively) rather than using ten direct
graphics commands to create a plot on the screen, starting over again
ten times till all parameters are correct, then switching to the PS
device, repeating my 10 commands, checking the file in Ghostview and
finally printing from there. Also, you can save your data along with the
plot in an .isv file, which I find useful.

By the way 1-- I have received only one tutorial so far, and that's been
three weeks ago. Did they forget about me?

By the way 2 -- I managed to get started on iTools with the iTools
User's Guide, even though it's not very clear at the beginning what
Windows, Views, Visualizations, Data Spaces etc. are and how they are
connected. The tutorial(s) definitely help to get started.

Cheers,
Benjamin

Speaking of which,

I signed up for the iTools tutorial, but, alas, find I have no time (yet.) Have
you been following it? If so, what do you think?

Cheers,
Ben
