Hello, I hope you have a good day...What MATLAB command can be used to display skeletal data in 3D from this matrix? He explained: The first line is related to the data recording time, and the second line is the joint number, and the third, fourth, and fifth lines are related to the x-axis, y-axis, and z-axis of the joint 0. It continues in the same way. How can the moving skeleton be displayed? Wrote? The data form is as follows.time, 0, joint0_x, joint0_y, joint0_z, 1, joint1_x, joint1_y, joint1_z, 2, joint2_x, joint2_y, joint2_z, .I know and have studied the skeleton display code on different sites, but I was confused about my own code. please guide me. tanx so much.

Try this:
data = readmatrix('human2_normal17_SkeletonData1.csv');
% Plot the first 4 joint skeletons.
PlotJointNumber(data, 1)
PlotJointNumber(data, 2)
PlotJointNumber(data, 3)
PlotJointNumber(data, 4)
function PlotJointNumber(data, jointNumber)
% Plot this joint.
column = 4 * jointNumber - 1;
x = data(:, column);
y = data(:, column+1);
z = data(:, column+2);
nexttile
plot3(x, y, z, 'b.-', 'LineWidth', 2)
grid on;
fontSize = 20;
xlabel('x','FontSize',fontSize);
ylabel('y','FontSize',fontSize);
zlabel('z','FontSize',fontSize);
caption = sprintf('Joint #%d', jointNumber);
title(caption,'FontSize',fontSize);
end

The concept is the same. You just need to read in your data. Then parse it into arrays for x, y, and z. Then use plot3 or plot to plot them.
