Hello everyone,

I'm looking to scatter two sets of data across a graph between specific points. I would like to scatter 9 points between x = 1.36 and x = 0.97 and I would like to scatter on the same graph 11 points of different size between x = 1.32 and x = 0.93. All the data points are at y = 0. How do I do this?

Thank you

Two cases:

Case 1: If the points are equidistant

x1 = linspace(0.97,1.36,9) ;
x2 = linspace(0.93,1.32,11) ; 
y1 = zeros(size(x1)) ; 
y2 = zeros(size(x2)) ;
 plot(x1,y1,'*r',x2,y2,'*b')

Case 2: If the points are random

x1 = linspace(0.97,1.36,100) ; 
x2 = linspace(0.93,1.32,100) ;
x1 = x1(randperm(100,9)) ; 
x2 = x2(randperm(100,11)) ; 
y1 = zeros(size(x1)) ;
y2 = zeros(size(x2)) ;
 plot(x1,y1,'*r',x2,y2,'*b')
