data = xlsread('data.xls');
column_data = data(:, 1); % replace 1 with the column number you want to plot
figure;
ax = axes;
plot(ax, column_data);
xlim(ax, [0, length(column_data)]);
xlabel(ax, 'Time');
ylabel(ax, 'Data');
while true
    % Read the latest data from the Excel file
    data = xlsread('data.xls');
    
    % Extract the latest data that you want to plot
    new_data = data(:, 1); % replace1 with the column number you want to plot
    
    % Append the new data to the existing data
    column_data = [column_data; new_data];
    
    % Update the plot with the new data
    plot(ax, column_data);
    
    % Pause for a short amount of time to allow new data to be generated
    pause(0.01);
end
