i often need to display X,Y,Z Data which are colored.
So far, i use
figure;
scatter3 (X,Y,Z, DotSize ,Z) ;
which delivers the desired result and is a single line of code (easy to remeber and usable on many different computers without implementing own stuff every time)
But the resulting graphs are very (and sometimes extremely) slow in reaction.
Even closing the graph is very slow.
A more potent graphic card does not have the slightest effect on that.
Is there another way to display X,Y,Z data colored and more efficient ?
Of course, i can use plot3, but then the data are not colored.
thx

Which version of MATLAB are you using? How big is the data?

This behaviour ocurrs in all Versions that i've used so far, as they where Version 2017 to 2021.
The data have differenz size. The maximum possible size is 2048x2048, but usually the data is much less in size.
Below, there is an example.
The Data consists of several patches, and they are combined in a loop like
figure;
hold on;
for i = 1:maxSize
scatter3(X{i},Y{i},Z{i}, dotSize, Z{i})
text(...)
end
