MATLAB Visualization CodeR
Use this MATLAB code you visualize data from a ThingSpeak channel.
readChannelID = 93156;
fieldID1 = 1;
readAPIKey = 'MCI6XM81ZFOY8UCE';

%% Read Data %%
[data, time] = thingSpeakRead(readChannelID, 'Field', fieldID1, 'NumPoints', 10, 'ReadKey', readAPIKey);

%% Visualize Data %%
thingSpeakPlot(time, data);
Particle Code for Sending Data to the ThingSpeak WebhookArduino
This code sends data to ThingSpeak from Particle devices
#define publish_delay 16000
unsigned int lastPublish = 0;

void setup() {

}

void loop() {
    unsigned long now = millis();

    if ((now - lastPublish) < publish_delay) {
        return;
    }

    int value = analogRead(A0);
    Particle.publish("thingSpeakWrite_A0", "{ \"1\": \"" + String(value) + "\", \"k\": \"XXXXXXXXXXXXXXXX\" }", 60, PRIVATE);

    lastPublish = now;
}
