Hi,
To plot 3D data without linking points across different sweeps, one effective approach is to use the ‘plot3’ function instead of the “surf” function . The ‘plot3’ function plots discrete points or lines in 3D space but does not automatically create a surface between these points.
To plot each sweep separately and avoid linking between them, you can loop through each sweep and plot them one at a time.
Please refer to the following example code to know how to plot 3D data using “plot3” function:
% Simulate some data for demonstration
% Let's assume we have 3 sweeps, each with 10 points.
numSweeps = 3;
pointsPerSweep = 10;
M0dBmto15dBm_0offset_1msdelay = array2table(rand(numSweeps * pointsPerSweep, 4)); % Random data
% Convert table to array
M0dBmto15dBm_0offset_1msdelaya = table2array(M0dBmto15dBm_0offset_1msdelay);
% Preparing data for plotting
X = reshape(M0dBmto15dBm_0offset_1msdelaya(:,1), pointsPerSweep, []);
Y = reshape(M0dBmto15dBm_0offset_1msdelaya(:,2), pointsPerSweep, []);
Z = reshape(M0dBmto15dBm_0offset_1msdelaya(:,4), pointsPerSweep, []);
% Plotting each sweep separately
figure; % Create a new figure
hold on; % Keep the plot window active to plot multiple sweeps
colors = lines(numSweeps); % Get some colors for the sweeps
for i = 1:numSweeps
plot3(X(:,i), Y(:,i), Z(:,i), 'o-', 'Color', colors(i,:)); % Plot each sweep with a unique color
end
hold off; % No more plots will be added
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');

grid on; % Add a grid for better visualization
Please refer to the image below to see the 3D output of the above code:
Kindly refer to the following MathWorks documentation to know more about the “plot3” function: https://www.mathworks.com/help/matlab/ref/plot3.html?searchHighlight=plot3&s_tid=srchtitle_support_results_1_plot3
I hope the information provided above is helpful.
