The above might be similar.

Thanks for these informative Matlab videos!

I have a question. I would like to do exactly what you did except my data is not on a grid. I have a list of x, y, z coordinates with a scalar field defined at those points; however, the points are not on a uniform grid such as that created by “meshgrid.” I’d also like to look at the planar slices of that field as separate 2D objects either with a colormap or with contour lines.

My first thought was that I could interpolate my output data values so that I have a grid. Looking at the function “interp2,” however, it turns out that I already need to have a grid of points to interpolate.

I have searched online for this answer and have no clue where to turn next. Any advice pointing me in the right direction would be helpful.

Thanks!
