<p class="MsoNormal"><span style="color:#1f497d">Just a follow-up. I have learned that fill color between 2 adjacent lines with Ngl.xy works nicely for an exclusive xy plot. However, it does not work as an overlay to a contour plot when sfXArray/sfYArray or
sfYCStart/End/ and sfXCStart/End are used in the original contour plot. Individual xy lines with Ngl.xy can be overlain on a contour plot with no trouble, but fill color between them does not work.<u></u><u></u></span></p>

<p class="MsoNormal">Hi, PyNGL Users,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I’m trying to indicate the terrain profile on the attached cross section plot. I am able overlay an xy line (black, terrain top) and another xy line (red, ground surface), but am unable to fill color between these two lines. All the combinations
I have tried are not working. Below is my Ngl.xy code for the overlay. Any help is greatly appreciated.
