How to make a 3D scatterplot with perspective
显示 更早的评论
I need to create a 3D scatterplot that looks something like this:
Where X is left-right, Y is depth, and Z is height.
I have arrays of X, Y and Z points and have been playing with scatter3(), but need perspective in the Y direction to better show position, and other things like turning off the Z axes, etc. Is this possible?

For example:
set(gca, 'Projection','perspective')

Thanks, that fixed the perspective issue:
The remaining problems are: 1) turning off the X and Y grids in the Z dimension, and 2) reducing the amount of real estate given to the Z dimension and increasing it in Y.
My code is below. It seems that in scatter3(), the X and Y grids automatically extend up into the Z dimension. I haven't found a way to turn that off. The Z grid is actually off.
scatter3(x, y, z, s, coltab, 'filled');
set(gca, 'Projection','perspective');
set(gca,'color', [0 0 0]);
ax.XAxis.Color = [0.6 0.6 0.6];
ax.YAxis.Color = [0.6 0.6 0.6];
ax.ZAxis.Color = [0.6 0.6 0.6];
% ax.GridColor = [0.6 0.6 0.6];
ax.GridColor = [1 0 0];
ax.GridAlpha = 0.5;
ax.XGrid = 'on';
ax.YGrid = 'on';
ax.ZGrid = 'off';
ax.YTick = 0:1:ylimit;
xlim([-xlimit xlimit]);
ylim([0 ylimit]);
zlim([0 zlimit]);
view(0, 10); % azimuth elevation

I am confused by your picture. The dots all look the same size. Didn't you want faraway dots to look smaller and closer dots to look bigger?
