My channel is at: https://thingspeak.com/channels/957733

Its an arduino fridge controller. It has three fields, temperature, humidity and mode. The fridge is used for charcuterie, so I have different modes for the different stages of the process. I have set 6 diferent values for the mode field, from 1 to 6.

I change the visualization title using this code:

modo = thingSpeakRead(957733,'Fields',[3]);
if modo == 1
    title('Heladera en modo Fermentado');
elseif modo == 2
    title('Heladera en modo Estacionado');
elseif modo == 3
    title('Heladera en modo Madurado');
elseif modo == 4
    title('Heladera en modo Heladera');
elseif modo == 5
    title('Heladera en modo Cava');
elseif modo == 6
    title('Heladera en modo Manual');
    
end

Is it possible to trigger an update when the mode changes? at the moment the only way the visualization title changes is when I refresh the browser page, it doesn't update like the plot does.

Thanks

If you have a paid ThingSpeak license, you can have the MATLAB viualizations auto update by simply enabling a checkbox setting. See documentation here.
