  1. I believe you mean to make a scatter plot. You need to use the scatter function. If that is the case, you do not pass on a 'Color' argument. The following should work for you: scatter(x_dis,y_dis,[],dis_color(1:nDis,:),'.') The [] is a placeholder for marker size. Do you initialize dis_color elsewhere? You may wish to do that before your for loop
  2. Between X values 1 to 14, the entire plot would be red, between 14 and 29 it'd be blue, and past 29 it'd be yellow. I'd prefer if you pointed me in the right direction instead of just giving me code for this question, I really wanna learn how to do this because it's not something they taught in my coding course
