How to display skeleton data

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

hello, tanx for your answer, I don't mean the 3D display, I mean the skeleton display related to this data,which can be connected with the following command to give such a skeletal shape. But I don't know how to form X, Y, and Z.

SkeletonConnectionMap = [ [4 3]; % Neck

[3 21]; % Head

[21 2]; % Right Leg

[2 1];

[21 9];

[9 10]; % Hip

[10 11];

[11 12]; % Left Leg

[12 24];

[12 25];

[21 5]; % Spine

[5 6];

[6 7]; % Left Hand

[7 8];

[8 22];

[8 23];

[1 17];

[17 18];

[18 19]; % Right Hand

[19 20];

[1 13];

[13 14];

[14 15];

[15 16];

];

line(X1,Z1,Y1,"LineWidth",1.5,"LineStyle","-","Marker","+","color","r");view(3)

Hello Dear, Let me tell you more clearly how I can convert the human2_normal17_SkeletonData1.csv(66*101) matrix into a 24x1 matrix with 25x3 in each row. In fact, the information related to raw numbers 1 to 25 in the main matrix and column 3 are the information related to X, Y and Z, which are placed in front of the main numbers(that exist in human2_normal17_SkeletonData1 matrix) . Do you understand what I mean? Thank you in advance for your cooperation.

Just ignore the information about the first column of the human2_normal17_SkeletonData1.csv matrix. In fact, the new matrix obtained has 66 rows and one column, where we have a 25x3 matrix in each row.

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.
