Name-value pair: If you set this property as a name-value pair with the “plot” function, you must set it after all the x,y pairs. The SCATTER function expects its 'S' parameter to contain the marker area in points squared. The way you specify the size depends on how you specify x and y, and how you want the plot to look. since you're using scatter one way around this is by doing this: r1 = randi(10,1,10); r2 = randi(10,1,10); a = 30*randi(5,1,10); bubsizes = unique(...
