4D plot of 3 vectors and 3D array
显示 更早的评论
I have a 3D array that is dependent on the variables of 3 different vectors. I am trying to make a plot with the axises being the vectors and likely color being the 3D array. Each vector is 10 long and the 3D array is a 10,10,10 array of values that are not a direct equation from the vectors.

Something like this? https://www.mathworks.com/help/matlab/ref/coneplot.html

Perhaps the slice function? https://www.mathworks.com/help/matlab/ref/slice.html

In this project, I show a couple of 3D vis techniques
Try:
[Ny,Nx,Nz] = size(data);
[x3d,y3d,z3d] = meshgrid(1:Nx,1:Ny,1:Nz);
s = data; % this if you want to normalize it -> 0.5*(data(:)-mean(data(:)))/std(data(:))+0.5;
s(s<0) = nan;
% s(s>1) = 1; % this is useful if you normalize it
figure();
hs = scatter3(x3d(:),y3d(:),z3d(:),0.5*s(:), ...
s(:),'filled','MarkerEdgeColor','none', ...
'MarkerFaceAlpha',0.05), view(-60,60);
axis equal
axis tight

is there a way to process this function if the data includes negative values?
Scatter3 can not used with negative values
and surface can not be used with vector
i do not know how i can show the data
