Hey,
I got some points in a 2-dimensional space from two different classes. I got a label vector to identify which points belong to which class. Now I would like to use this label vector, to change the color of the points belonging to the second class, after having made a scatter plot. How do I do this, without having to separate the code in two scatter commands?

One of the inputs to the scatter function is a list of colors for the different data points. Just make it up however you'd like and pass it in.

I got it to work, thanks for the assistance. In case you're still curious on the second question: It is because the I'm making a program for classification. The classification isn't done initially, but rather when the user clicks a button. Hence the points should not change color until this time.
