Below is my code which I wish can change the color for the visualization without refresh the page.
% Set your ThingSpeak channel and API keys
channelID = 2044216;
readAPIKey = '4SVDGTR02R02PFAD';
% Initialize variables
threshold = 0;
circleRadius = 6;
circleCenterX = 30;
circleCenterY = 40;
greenColor = [0 1 0];
redColor = [1 0 0];
% Create the circle visualization
figure('Position',[100 100 200 200]);
circle = rectangle('Position',[circleCenterX - circleRadius, circleCenterY - circleRadius, circleRadius*2, circleRadius*2],...
'Curvature',[1,1],'FaceColor',greenColor);
axis square;
axis off;
% Continuously update the circle color based on the ThingSpeak channel data
while true
% Read the latest value of field 2 from your ThingSpeak channel
fieldData = thingSpeakRead(channelID, 'ReadKey', readAPIKey, 'Fields', 2, 'NumPoints', 1);
% Update the circle color based on the value of field 2
if fieldData == threshold
circle.FaceColor = redColor;
else
circle.FaceColor = greenColor;
end
end

You cannot continuously run your MATLAB code in ThingSpeak. There is a timeout for all MATLAB code, somewhat longer for paid users but still only long enought to complete one calculation. Use react or timecontrol to regularly trigger the display to refresh.
