DPlot

Good morning. I'm not sure if this has been asked and answered already.

I'd welcome any thoughts on how to plot this. I need to plot a celestial body trajectory with azimuth and altitude above the horizon, both in degrees, over time. I would picture the plot as hemispherical with azimuth on the horizontal scale, elevation on the vertical scale and time (GMT) on the concentric scale.

Any suggestions?

Thanks

DPlot doesn't work with polar coordinates in 3D, but you can translate those to cartesian coordinates easily enough if you have Excel or something similar with x = r*cos(azimuth) and y = r*sin(azimuth).

Thanks David. That's what I was resigned to do, I just thought it would be a lot prettier on the polar plot.

Thanks for getting back to me so quickly.

Cheers
