Plotting 4D data

Dear MATLAB Users,

I have the following matrix,

197.32 5.963 4.427 1.245

179.91 5.867 4.615 1.127

124.75 5.833 4.725 0.779

91.65 5.785 5.175 0.714

150.94 6.113 4.322 1.688

66.89 6.322 4.006 2.104

18.32 6.498 3.932 2.579

Where column 2, column 3 and column 4 are coordinates of my system and column 1 is the time. I want to plot the coordinates and use column 1 as a color map. Kindly suggest the way.

Thanks in Advance ,

You could use plot3 in a loop.

Try something like this:

t = M(:,1);
x = M(:,2);
y = M(:,3);
z = M(:,4);
scatter3(x,y,z,32,t,'filled')
