можно ли сделать так, что бы сетка отображалась поверх 3D графиков?

вот например есть график

я хочу что бы сетка была на переднем плане и накладывалась на изображение

"Is it possible to make the grid appear on top of the 3D plots?"

For example, this figure

<image>

I want the grid to be in the foreground and overlay the image

I was going to suggest setting the Layer property but that is only for 2d views

[Walter Roberson]

you could perhaps create a second axes with color 'none' on top of the first, with linkaxes so that they rotate the same way, but the empty axes would be visually on top

[Pavel Kuzmitsky]

I don't quite understand how to do this, can a simple example? I get it so that the axes on top of the drawing completely cover it and it is not visible. Is it possible to create drawings that are superimposed on top of the previous ones, but are transparent? For example, I would add a surface to this drawing, which would be a transparent grid, that is, the holes in the grid are transparent, and not the grid itself

Answer 1

[Walter Roberson]

fig = figure();
ax1 = axes('Parent', fig);

[X, Y] = meshgrid(1:50, 1:60);
Z = X.^2 + Y.^2 - cos(X.*Y);
surf(ax1, X, Y, Z, 'edgecolor', 'none');

ax2 = axes('Parent', fig, 'color', 'none', 'gridalpha', 1);
linkprop([ax1 ax2], {'Position', 'XLim', 'YLim', 'ZLim', 'View'});
grid(ax2, 'on');

Here the grid is on top of the surface. It is a bit difficult to tell that it is not the case that the surface is transparent with the grid below it, but in that case the grid would not appear as dark as it does here.

I would add a surface to this drawing, which would be a transparent grid, that is, the holes in the grid are transparent, and not the grid itself

You would not be able to do that just by using "grid on": there is a single grid alpha that is for the entire grid, with no way to make it selective. You would therefore have to draw the grid, such as using a surface or patch. For example surface with 'EdgeAlpha', 'interp' and 'AlphaData' being a 2D array the same size as ZData.

If you use that, then you do not need two axes: you can use a single axes with SortOrder set to 'childorder' https://blogs.mathworks.com/graphics/2014/11/04/sortmethod/
