[Plplot-general] plplotlib ... fine :-)

[Oliver B. <ol...@fi...>]

Hello,

I recently found the plplot-library
and yesterday had started to explore it.
It's really nice to use it.


But btw, during my first experiments I found
that it crashes wif not used in the correct way
(for example changing two functions in order).

Would be fine to fix such things. I also found some
bugs on displaying data, when rotated.

Would be fine when these things could be bugfixed.
When I encounter errors, at least during this exploration stage,
I save the c-code as well as the example-results.
When I hav a couple of them I may send them to the developers or to a
bugreporting tool, if there is one in use.

For now I want to say that it's a fine library even
in the presence of these problems.


In the archive I found someone who wrote that he
wants to write an OCaml-binding for plplot.
That's fine. I had the same thing in mind, when looking
at impressive the example-page of plplot. :-)
But I also will be patient on the results ;-)

Ciao,
   Oliver Bandel

Oliver,

I posted to the list recently about OCaml bindings for plplot.  They
can be downloaded from http://ocaml-plplot.googlecode.com/ - if you
are using OCaml installed from anything other than GODI I would
recommend getting the latest code from the Subversion repository as it
no longer requires a patched camlidl, while the released tarball needs
extra patches which, I think, only exist in the GODI OCaml
distribution.  I will make a proper new release once I finish up a few
more features to make the coverage of the bindings (I think) complete.
 If you try the OCaml bindings please let me know how they work for
you!  I would be happy to hear about it and answer any questions which
may come up.  Here is an example plot made with the OCaml bindings:

http://www.atmos.umd.edu/~hcarty/example_plots/trmm_july_climatology.png

The code for the color bar in that plot is in the extras.ml file in
the Subversion repository.  There are currently two examples in there
as well, translated from the C examples.

PLplot is a very nice library and I hope you enjoy it!  It has
certainly made my research more pleasant.

Yes, that was, what I meant with the mails/postings in the archive
of this list.

I tried the code, but could not get it compiled.
I stopped then and switched back to C.
My main intent now is to understand how to use
plplot-lib.
When I know it in C, then I can try to use it in COaml.

Often I had some problems of adapting external OCaml-libs,
because a lack of documentation.
I always want to be able to use the lib, even if there
are OCaml-bindings... they might be not compilable (or only
with too much effort), or might be documented not so well,
or any other reason.

When I then know how to use it in C, I can try to do it
in OCaml also. Then I can hope, the functions have similar names ;-)

Oh, very nice. :-)

Yes, I agree, it's a nice lib. :-)
Fine that you have mor fun in research then. :-)

I think about possibly studying again.
Then this plplot-lib could help a lot. :-)
Otherwise in commercial programming projects you
often have much limitations in what is alowed
and what not, and they're often boring.

Ciao,
