Reading HDF5 files? Plans?

[Alex van der Spek]

I was wondering if there are plans to add HDF5 capability to gnuplot.

I realize HDF5 is a very rich format. Won't be easy to write a general
interface but something like:

gnuplot>>> splot 'foo.hdf5' 'dataset name' using 1:2:3

or

gnuplot>>> plot 'foo.hdf5' 'dataset name' using 1:2:

might be possible?

Incidentally it would immediately include the capability to plot *.mat files
too as the latest version thereof are nothing but HDF5 files in disguise.

The HDFgroup provides the API to HDF5 files, that can't be the problem.
Coming up with a sensible implementation in gnuplot script language will
require some thinking and talking, though.

Having acquired a reasonable understanding of HDF5 I would offer support and
help to develop this if this is seen as worthwhile to develop.

I can't comment on that, but

you can do such thing with

gnuplot>>> splot '< h5totxt -s " " -d name' using 1:2:3

using e.g. the h5utils
<http://ab-initio.mit.edu/wiki/index.php/H5utils>, I use that for all my
data.

So I don't know if there is really a need to implement this in gnuplot.
I guess a very simple interface to extract only datasets by name could
make sense, but not a general interface.

That's a solution for Linux/Unix only!

Nevertheless, thanks much! I wasn't aware of the MIT h5 tools.
