2D plot with 3 var

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 :

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.

Thank you so much.... I tried this but didnt use the Pointsize, that's why didnt work.

Thanks again!
