Re: How to plot a southern hemisphere TC symbol on a time-longitude plot. [SEC=UNCLASSIFIED]

Hi Joan,

The NCL team has been discussing this offline a bit. We have a NH TC symbol, but no SH TC symbol, which seems like an oversight.

We are looking into creating a new function, or modifying NhlNewMarker such that you could rotate any marker in our font tables. This would allow you
to take the existing NH marker, and flip it 180 degrees to turn it into an NH marker.

And yes, you can use NhlNewMarker to plot a symbol on any plot you want. Use gsn_add_polymarker to attach the marker to the plot, using coordinates that are in the same dataspace as the plot you're attaching it to.

See the attached script, which creates a "blank" plot whose axes both go from 0 to 1. I used positioning coordinates between 0 and 1 to position the three markers.
