<div dir="ltr">Stuart,<div>It would help if you shared the portion of your script that you used to attempt doing the 500mb height charts. What is the snag? What GrADS error are you getting?

<br>
Still rather new to grads but have managed to create some good charts running the GFS 0.25, however, I have hit a snag on the 500mb height chart. Ive scripted all the colour and shading, including the contour bar but the hgt500 code will not work. Does this need defining and if so can someone please share the definition. Also I'd love a jet stream chart, however, I am also struggling with that. Any info would be much appreciated. I've attached my precip & rainfall chart to show I'm not completely without hope :)<br>
<br>
Thanks in advance,<br>
