<p>Hi all,</p>
<p><br>
</p>
<p>Thanks to Rick Brownrigg for his help. That was really helpful!</p>
<p><br>
</p>
<p>Using the 2 following methods seem to work well:</p>
<p>- either both "delete(res)" and "delete(wks)" before each plot</p>
<p>- or a new "res" (like "res3" for a 3rd plot) and a new "wks" (like "wks3" for a 3rd plot) for each plot</p>
<p>I do get a figure with the things I want in it.</p>
<p><br>
</p>
<p>The only things remaining are the colours (to match with the legend of course)! I get 3 lines in "cyan", and 3 legend items in "cyan", while I do ask for several colours: e.g. res3@xyLineColor = (/"cyan","blue","green"/). Do you have an idea on how to sort
that out?</p>
<p><br>
</p>
<p>I attach a figure of what I get, so that you can visualise the small issue left.</p>
<p><br>
</p>
<p>Thank you,</p>

<div>Hi Maxine,<br>
<br>
</div>
A couple of comments:<br>
<br>
</div>
i) for each plot, you first set "opt = True", then either "res = opt" or "res2 = opt", and then assign a bunch of resources for the plot. But after the first plot., performing "res = opt" doesn't affect the values or presence of resources associated with "res"
from the previous plots. So for example, in one plot, you've set "res@xyLineThickness = 8", a scalar integer value. In a subsequent plot, where the error message arises, you set "res@xyLineThickness = (/ ..... /), an array of floats, and as you likely know
NCL won't allow reassignment of incompatible types.<br>
<br>
</div>
The solution would be to "delete(res)" for each plot.<br>
<br>
</div>
ii) In a similar vein, you are re-opening the workstation for each plot and assigning it to "wks". I'm not totally certain what the behavior is there, and whether the previous plots get written and closed out properly. As odd as it seems, performing "delete(wks)"
will close the plot/workstation. Alternatively, if the workstation is the same for each plot, its not necessary to reopen a new instance for each plot -- just open once at the top, and it will get closed properly when the script terminates.<br>
<br>
</div>
Hope that helps...<br>

<p>Dear NCL gurus,</p>
<p><br>
</p>
<p>I've used NCL for more than a year, but this problem seems to be particularly tough to solve, so I think I need to refer to you.<br>
</p>
<p><br>
</p>
<p>I've been working on a script for days, I've turned it in different ways (array of data, overlay, using a single y-axis, etc...), but I can't seem to find the solution. I had a script to plot several lines on the same graph, but these lines had exactly the
same x-axis. That was working fine. Now I'm trying to plot several profiles, that all have different x and y values, but I always receive the following error (after a bunch of warnings due to the fact that I'm plotting several types of plots with the same
script):</p>

<p>The netcdf files I'm using are just standard WRF output from an idealized quarter_ss type simulation. They are big files (~30GB) so I'd rather not add them now. If necessary, I'll put a few of them online.</p>
<p><br>
NOTE: If you wish to try the script on a smaller number of wrfout files, just change the num_day_max variable to a small number (I receive the same error in any case). If you don't use 90 files (as the target is), then some of the profiles in array_of_heights
and array_of_theta_prof may be undefined. But I have checked that this is not the reason for my issue, as I get the same errors when running on the full 90 files. To avoid this slight issue, you may run the cleaned version: plot_temperature_cleaned.ncl<br>
</p>
<p><br>

<p>For information, I'm using NCL v6.3.0.</p>
