Matlab 3D Scatter Plot

[ASidebottomIU]

Hello

I am very new to Matlab and need help on importing my data for a 3D plot. Currently, I have x,y,z data that I am trying to import to look like Figure 5 in the following paper:

I have no idea how to import the data from an excel file- any help would be appreciated. Thank you!

The issue is that I am not sure what the extra 's' and 'c' fields are that are required for Scatter3 (x,y,z,s,c). I want to relate both x and y to z- an actual step-by-step would be most helpful as I am struggling to relate the script to the plot tools gui.

S may be used to set the size of the dots on the scatter plot, and C may be used to set the color of the points. You can to learn this yourself using MatLab documentation.

But scatter3 will not produce a plot like either Figure5 a) or Figure 5 b).

To produce a plot like figure 5 a), you could use surface(X,Y,Z) (http://www.mathworks.com/help/techdoc/ref/surface.html), with the jet colormap (http://www.mathworks.com/help/techdoc/ref/colormap.html).

Figure 5. b) is 2d so one would just use scatter(X,Y,S,C) (http://www.mathworks.com/help/techdoc/ref/scatter.html) to get something similiar. You could use multiple calls to scatter with "hold on;" to plot the different colors or dot sizes.

Thank you MisterX for your reply- it definitely helped and I have figured it out!
