Cannot get figure using parfor in a loop

Hi,
I want to define the color of each arrow with function quiver3, but I have a large number of data(double 83041*1), so I used parfor as below:
But no figure returned, it works well when I use just for for loops.
Regards!
h = figure(1);
parfor n = 1:nPart
disp(n);
col = colors(vv(n),:);
quiver3(x_s(cal_step,n),y_s(cal_step,n),z_s(cal_step,n),u(del_step,n),v(del_step,n),w(del_step,n),10,'Color',[col(1),col(2),col(3)]);
end

It is not possible to plot to the display inside any parallel construct. The workers are in separate processes that do not have access to the graphics subsystem.
You would need to either calculate all the data in the “parfor” and then do the plotting after the “parfor” or you can plot in “parfor,” and then you can use “saveas” to save it to a file.
Below, I have attached link to a MATLAB Answers thread that discusses an issue similar to yours:
You can read more about “saveas” in the below attached link:
