Unrecognized function or variable 'thingSpeakPlot'.
Hello, I'm new to thingspeak, i want to combine 4 fields in one chart, i have used the code below
readChannelID = 1408944; % YOUR CHANNEL NUMBER fieldID1 = 1; % YOUR FIELD NUMBER ie 1 to 8 fieldID2 = 3; % my case 1 Temp 2 Humid readAPIKey = '19EJIJW6YBM7VS7N'; [data1, time1] = thingSpeakRead(readChannelID, 'Field',fieldID1,'NumDays',1,'ReadKey', readAPIKey); [data2,time2] = thingSpeakRead(readChannelID, 'Field',fieldID2,'NumDays',1,'ReadKey', readAPIKey); thingSpeakPlotYY(time1, data1, time2, data2,... 'YGrid1','on','YLabel1','% H.R.',... 'YLabel2','*C','XLabel','Fecha y hora',... 'Title','Tempix y Humix ultimas 24 horas');
However, an error occurs saying that the function thingSpeakPlotYY is unrecognized

That function (thingSpeakPlotYY) has been deprecated for some time. Can you let us know where you found the code? You can use yyaxis instead.
Yes, i found the link in youtube video: Here is the link of the code: https://www.mathworks.com/matlabcentral/fileexchange/71908-air-quality-measurements-and-visualizations?s_eid=PSM_15028
Thanks for sharing the file exchange post. I don't see thingSpeakPlotYY in that file exchange code. If you can find the you tube video, can you please share it?
Sorry, i have pasted the wrong link, Here is the right one : https://community.thingspeak.com/forum/thingspeak-apps/how-to-have-multiple-field-data-in-one-graph/
I really appreciate that! I have put off the work of culling posts in the old community, and this provides some inspiration. Let me know if you are able to get what you need working with yyaxis right.
Thank you, i have managed to do it using yyaxis. however i'm wondering if i can make the appearance of the generated graph as field graph appearance. Another question is how can i make the matlab visualisation in real-time.
