Hi all<br>
<br>
I am a newcomer to pyngl-talk (and PyNGL) but I read the July 2019
thread on that subject (PyNGL in Jupyter notebooks). [However, I
was not able to fit the present message i the thread ]<br>
<br>
I am in the case of Mark England, namely getting error messages such
as "<i>Only one instance of ErrorClass is</i><i> supported" </i>when
trying to rerun some code cells producing graphics.<br>
<br>
What I discovered is that :<br>
<ol>
<li>avoiding the call to Ngl.end() seems enough to avoid the
problem<br>
</li>
<li>for the case of a png type workstation, there is no need to
call delete_wks() in order to get a well-closed png file;
calling frame() is enough (and necessary); this is compatible
with the description of delete_wks, which should be used to cope
with th elimit in the numbers of opened workstation.<br>
</li>
<li>for the case of an x11 workstation, the example provided by
Karin is not working; at the best, a small par of one latitude
circle is drawn (after a draw() and a frame() - a delete_wks()
just closes the x11 window)<br>
</li>
</ol>
<p>By the way, I have a more general question : where can I find a
description of what is not available in pyNGL (w.r.t. full Ncl) ?
<br>
</p>
<p>Thanks if you can help on bullet 3 and last question</p>
<p>Regards<br>
