1. The problem statement, all variables and given/known data

I have 4 rows of data for a single entity in excel file
2. Relevant equations
i want to plot all the 4 rows in a single figure in matlab

3. 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?

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.

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:
