This code working fine.

readChannelID = [1788078];
fieldID1 = [1];
readAPIKey = '';
[data, time] = thingSpeakRead(readChannelID, 'Field', fieldID1, 'NumPoints', 30, 'ReadKey', readAPIKey);
plot(time, data);

But this code, have error : "Unrecognized table variable name 'x1'."

readChannelID = [1788078];
fieldID1 = [2];
readAPIKey = '';
[data, time] = thingSpeakRead(readChannelID, 'Field', fieldID1, 'NumPoints', 30, 'ReadKey', readAPIKey);
plot(time, data);

What i do wrong? Thanks.

I think it is related to the special characters in the field names. Thank you for reporting this, we will look into it further. In the meantime, can you change your field names to have all standard latin characters and let us know if that fixes the issue?
