If I use this line of code:
[data,timestamps,channelInfo] = thingSpeakRead(12397,Fields=[1,4],NumMinutes=5)
I correctly see values, timestamps and Channel Info. In particular, Channel info shows the fields: Latitude and Longitude with some correct values (inserted via "channel setting" when the channel was created).
Now, if I run the following example using geoscatter(...):
mapData = thingSpeakRead(12397,'Location',1,'numpoints',37,'location',1,'outputformat','timetable');
geoscatter(mapData.Latitude,mapData.Longitude,'r');
I don't get any position on the map, since the latitude and longitude values are: NaN
So the question is: should I add 'latitude' and 'longitude' any time I write a data in the channel? So, what are the two fileds 'latitude' and 'longitude' of Channel Info used for? are they not available for the geoscatter() function?
Thanks
Fabio
