I have a dataset that can be divided into either 3 groups, grp_A1, grp_A2, and grp_A3, by criteria A or meanwhile 3 different groups, grp_B1, grp_B2, and grp_B3, by criteria B.
I wish to visualize this using MATLAB. The desired visualization should contain circles enclosing the data points according to the points' membership.
For example, consider a simple dataset containing 4 points
[pt1 pt2 pt3 pt4]
By criteria A, pt1 and pt2 belong to grp_A1, pt3 belongs to grp_A2, and pt4 belongs to grp_A3. So one red (red for criteria A) circle encloses pt1 and pt2, a second red circle encloses pt3, and a third red circle encloses pt4.
Yet by criteria B, instead of being in the same group as pt2, pt1 is in the same group as pt3. Hence, there should be one blue (blue for criteria B) enclosing pt1 and pt3, one enclosing pt2, and one enclosing pt4.
How should I do this in MATLAB?
Update
What makes the problem complicated is that my data points are high-dimensional, meaning that I will also have to figure out a way to "reasonably" present them in 2D. By "reasonably", I mean I should sort of arrange them in such a way that the circles do not look messy.
