I don't see a way to feel isolines at different altitudes. From various comments I see people talk about isolines at different altitudes or pressures. But I only see what I think is the surface pressure isolines. Changing altitudes with the slide bar does not change the isolines at all. I've tried it with all the models and have the same results.
