2D scatter plot with Z-value in color

Hi all,

It’s a basic question but I struggle to find the answer on the Internet...

I have a matrix with x,y and z colum, representing the c-coordinate, the y-coordinate and depth (z).

I’d like to plot (x,y) but that those points show a colorscale depending on the depth value (just the point colors I don’t want an interpolation).

Can somebody help me please?

Would anyone be able to tell me how to do this but then interpolate the colours?

pointsize = 10;
scatter(x, y, pointsize, z);

Great thanks! Do you know how I can set full points and not just the border?

[Saskia]

OOuupsss got it.

Thanks again!

Thank you.

I managed to color the points (with the default color scheme) according to a third variable. However, how can I change the colour scheme? And ho can I get a legend with a color bar?

Cheers

Is there a possibilty of getting this visualization with a color bar?

[alberto caracciolo]

Yeah, that is basically my same question!

Hi. Could you tell me how you did color gradient with z value?

[Mateusz Surma]

Not sure if you still need the color bar:

cb = colorbar();

Thank you!
