Greetings Stephen, Are you wanting to plot wind barbs or vectors, or just wind speed? Also, are you wanting to look at model output or RAOB data? Also, if you are somewhat new to the IDV, you may find the tutorial useful (it's what we cover in our training workshop): https://www.unidata.ucar.edu/software/idv/docs/workshop/ Cheers!
