<span>Dear Dave,<br>
</span>
<div> thanks for the informations!<br>
</div>
<div> Up to now in my julia program for some tasks (like represent vector fields, ...) I'm calling ncl scripts from julia with the 'run' function (command for Running External Programs similar to NCL's systemfunc())<br>
</div>
<div><br>
</div>
<div> I still have to try to import the PyNGL library but I will try it!<br>
</div>
<div><br>
</div>
<div> I know that in julia you can import other library build in other language<br>
</div>
<div> (for example my colleague use the python visualization PyPlot and Seaborn library)<br>
</div>
<div> <br>
</div>
<div> I'm not expert but perhaps you need a wrapper to use an external library ...<br>
</div>
<div><br>
</div>
<div>thanks<br>
</div>

<div dir="ltr">Oops. I meant to say, "This would also depend on whether the <b>NCAR Graphics</b> runtime system is compatible with the Julia runtime system."</div>
<div dir="ltr"><br>
</div>
Also you might consider calling <b>PyNGL</b>, the NCAR Graphics Python interface, directly from Julia. One again, there would be runtime compatibility concerns. These may be uncharted waters.

<div dir="ltr">Ah. Here we go. The Julia home page, <a href="https://julialang.org" target="_blank">https://julialang.org</a>, says "... you can easily use libraries from Python, R, C/Fortran, C++, and Java."</div>
<div dir="ltr"><br>
</div>
<div>So theoretically you should be able to use either the C or Fortran interface to NCAR Graphics, or even mix them. This would also depend on whether the NCL runtime system is compatible with the Julia runtime system. This would be worth testing. If you
try anything like this, let us know what happens. Thanks.</div>

<div dir="ltr">Franz, NCAR Graphics has C and fortran interfaces. But I do not know anything about Julia. Are any of these options possible?</div>

<div><br>

<div>* Julia calls C.</div>
<div>* Julia calls fortran.</div>
<div>* Julia calls a command shell, like NCL's systemfunc().</div>
