[Kst] Contribution NetCDF-interface: --> plotting of PACKED/COMPRESSED DATA and MATRIX COMPONENTS

[Rix, Patrick]

Hi Nicolas,

Cool - that's a good news !
..ignoring coding conventions to some extend was what I meant by the term 'hack'. This was a quick-and-dirty solution intended as test to find out if plotting of matrix components works at all. The better and cleaner solution would have been to implement some sort of data access dialog for choosing certain components of matrices and derive a vector out of it which can be plotted. (I found in kst some matrix data accessing functionality  in the View->Matrix section of the main menu showing the data in tabulated form - but unfortunately I found no way to create a vector from a single row or column of the matrix.)
Maybe you or someone else has an idea for a cleaner and more elegant implementation in the code.

Can you send me a note when the new feature appears in the official main stream, i.e. when it  will be available for download in the new KST-executable release ?
I plan to announce KST on the MBDyn user mailing list as a new plot tool for the binary files of multi-body simulations.

Salut,
Patrick.

Hi Patrick,

MANY THANKS for your efforts and the contribution!
I still hadn't had time to do it myself, but reviewing your code and integrating it should be much faster than actually writing it :-) I've just had a quick look and apart from different coding conventions it looks quite OK.

Today's a good day for Kst:
- Barth seems to have more time for Kst again
- We have a very nice contribution from you, which should make it into 2.0.7
- I came across this nice blog post on planetkde.org which mentions Kst: http://knro.blogspot.de/2013/03/say-hi-to-j065143540858.html

Cheers,

Nicolas
