Usage of a single color while plotting using scatter3
显示 更早的评论
Hi, I am trying to plot a four dimensional array using scatter3 command. My interest is to show one of the dimension varying the intensity of the same color e.g. light red to dark red. However I am not yet successful. I have attached my code below.
clear, clc;
i=importdata('wp1_param.txt')
p=i.data(:,1);
x=i.data(:,2);
y=i.data(:,3);
z=i.data(:,4);
data = [x;y;z]
c = [1:31]
colorbar
scatter3(x,y,z,100,p','filled')
A solution to the above problem will be highly appreciated.
Thanks

No problem here in my test:
p = sort(rand(50,1));
x = linspace(10,30,50).';
y = logspace(1,sqrt(2),50).';
z = sqrt(x.^2 + y.^2);
scatter3(x,y,z,100,p,'filled')
There was one recent release in which the colors of scatter markers could be wrong; see http://www.mathworks.com/matlabcentral/answers/242962-legend-entries-all-same-color-in-matlab-2015b if you are using R2015b.

When you say that it did not work, what output did you get? I have attached what I get.
What does
opengl info
return for you? Do you happen to be using an Intel HD2000 graphics card?
