4D plot of 3 vectors and 3D array

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

Its not velocity vectors, the 3 vectors are pressure, length, diameter, and the 3D array is cost. I want a graph to show the cost for each combintation of length diameter and pressure and the cost associated with that combination.

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

In this project, I show a couple of 3D vis techniques

https://www.mathworks.com/matlabcentral/fileexchange/71774-create-measure-characterize-visualize-1d-2d-3d-fractals

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
