Hi,
I want to make a scatterplot of x, y, z coordinates and include the weight (which differs per particle) the locations have. So every particle has a specific weight and I want to combine all the weight of all the particles that have the same coordinates and visualize it as a heat plot. Is this possible?
Thanks!

You could pass color values as follows
n = 1000;
X = rand(n, 1); Y = rand(n, 1); Z = rand(n, 1); C = hypot(X, Y);
size = 500;
scatter3(X, Y, Z, size, C, '.');
colormap jet
Or do you want to take a slice along the xy-plane? Then you should probably look at this page .

Hi, Please did you find out how to directly add weights to data points, especially depending on a condition? And also the consideration of data points of same location?
I will appreciate your feedback. I am struglling with this aspect. Thank you.

Do you want to add the weights to the color or to the size of the data points? In what way should they depend on a condition? Please state your problem more clearly.
