I tried to display multiple 3d grids in one Graph. There were two problems: 1) First I wanted to use two seperate layers on top of each other, but I could not find a way of adding another 3D Layer, i always got a plain 2d layer on top of the already created 3d layer.
2) so I just added the matrix data into the first layer (worked fine..) But the intersections between the 3d grids is not correct (the second is always drawn last and on top, although its lines should be partially behind the first one.
Is there a way of creating visually correct intersection 3D surfaces / grids ? (maybe in version 7.5 ?) Is there a way of using half-transparent 3d surfaces so datapoints / or other grids behind it shine through ? GG
