Visualize 4D data from pressure measurement

I'm taking measurement samples from a 3D space X,Y,Z. Each points has a corresponding preassure value.

The distance between each point on the x-axis is the same. Same for the other two axis.

Now I'm struggling with displaying the values.

I've found following code in the file exchange which seems to fit me needs:

But how am i supposed to store my measurepoints in a 4D matrix?

I'm aware of the slice function where x,y,z (Each 1D) would contain my position values and the v 3D matrix contains each corresponding value.

I'm not able o transfer this knowledge to the code from the file exchange.

You could consider volumeViewer()

Since im using a laptop which doesnt meet the minimum requirement for the volumeViewer this is not an option at the moment.

EDIT: i tried it on another machine and it seems to be perfect with only one thing missing, a different colormap like jet.

I have used this function on the fileexchange in the past and I think it is really good:

But if there is some sort of pattern to your data (i.e. there are blobs or areas of high values) then you might be more interested in this method:

Thanks for your reply.

isosurfaces dont seem to fit my needs. slice would be perfekt but i need sliders to navigat through the different slices. found something which seems to fit perfectly but doenst work for me right now because of an error.

vol3d could be good as well i'll have a look at it later thanks!
