Hi!
I have 3 vars:
x: Position x of the particle
y: Position y of the particle
v: Velocity of the particle
So... If I plot:
plot(x,y,'.')
I have this :
muestra.jpg
I need the same plot but the colors of each point in a color related to the velocity.... For example the points where the velocity is high red and the points where the velocity is low, blue. Hope it's understood.
How can I do this?
PS: In the plot there are 7200 particles

Pointsize=10;
scatter(x(:), y(:), Pointsize, z(:))
And you might need a call to colormap() to get the coloring you want.
