Hi, thanks for getting in touch. Unfortunately what you want want to do is not currently possible in THREDDS. The charting methods of THREDDS are really designed for people who want a full chart, rather than a view onto the data.

I think that your best option would be to grab a subset of the data via the data access methods of THREDDS, that way you can plot the chart in whichever package you're most comfortable with.
