I am working on showing the coordinate on the map in my ThingSpeak channel. However, it only allow to show 1 coordinate on my created map. How should I hold the previous coordinate, then adding multiple coordinate continuously without refreshing the webpage? (Paid license account)
Hopefully someone can provide your suggestion to me. Thanks in advance.

I recommend writing the position data to your channel feed in the latitude and longitude fields.
Then in your MATLAB visualization, use thingSpeakRead, and set the name-value pair 'location' to true.
now you can use geoscatter or any of the other great mapping functions to plot your data.
