Plotting Excel Data in Matlab: How to Combine Multiple Rows into One Figure

[ppmko]

Homework Statement

I have 4 rows of data for a single entity in excel file

Homework Equations

i want to plot all the 4 rows in a single figure in matlab

The Attempt at a Solution

i know how to import the excel data but can find a figure or a function where i can plot these 4 rows in a single circle. scatter plot looks odd too clumsy. is there anything better

Sorry, I'm unclear of what you're asking here.

Are you attempting to plot a pie chart?

Or are you trying to plot several data sets on the same graph?

 

[ppmko]

I have 4 sets of data of points with x,y,z coordinates in an excel file
I want to plot all the data points in one plot
and I want all these points to be inside a circle.

Well, you can plot points in 3D in MATLAB using the plot3 function:

I don't understand what you mean by plotting the points inside a circle, however. Unless you mean that the points are coordinates of a circle in 3D space. Otherwise, they'll just be a bunch of random points in 3D space.

 

[ppmko]

Yes these are coordinates of points inside the circle. I know plot3 but that just creats circle. i want these coordinates inside the circle.

Ah, I think I see. You want to only plot the data points, and not have MATLAB automatically join these points together? Well, you can do that just by changing some of the LineStyle properties:
