使用未记录的Axes.Backdrop
属性,您可以获得此行为。 Axes.Backdrop.Face.VertexData
包含背景顶点列表。我们可以找到并保持最佳状态:
ax = gca;
face = ax.Backdrop.Face;
% can be replaced with conditions on other axes and limits
point_on_face = face.VertexData(3,:) == ax.ZLim(1);
is_target_face = all(reshape(point_on_face, 4, []));
target_face_verts = logical(kron(is_target_face, ones(1, 4)));
% discard all but the first quad (the floor)
face.VertexData = face.VertexData(:,target_face_verts);
但是,当轴旋转时,这些四边形会被重新绘制,这不是一个有效的解决方案。
我们可以通过添加事件监听器来进一步:
function h = set_walls(ax, varargin)
function update()
face = ax.Backdrop.Face;
data = face.VertexData;
if empty(data); return; end
keep_verts = false(1, size(data, 2));
for side = varargin'
side = side{:};
switch side
case 'xmin'; point_on_face = data(1,:) == ax.XLim(1);
case 'xmax'; point_on_face = data(1,:) == ax.XLim(2);
case 'ymin'; point_on_face = data(2,:) == ax.YLim(1);
case 'ymax'; point_on_face = data(2,:) == ax.YLim(2);
case 'zmin'; point_on_face = data(3,:) == ax.ZLim(1);
case 'zmax'; point_on_face = data(3,:) == ax.ZLim(2);
otherwise; error('Unknown face');
end
is_target_face = all(reshape(point_on_face, 4, []));
keep_verts = keep_verts | logical(kron(is_target_face, ones(1, 4)));
end
face.VertexData = data(:,keep_verts);
end
h = addlistener(ax, 'MarkedClean', @(x, y) update);
end
这闪烁,但它有效。该函数可用作set_walls(gca, 'zmin')
