How to avoid objects from function "arrow3" to be plotted on top?
显示 更早的评论
Hi! When using the Matlab function "arrow3", the resulting objects always come on top, no mather what I do. In the script below I want the blue and green marker on top of the red arrows. Is there anything I can do to achieve this? Thank you!
x1 = 0; x2 = 2; xs = 0.2;
y1 = 0; y2 = 6; ys = 0.5;
[x,y] = meshgrid(x1:xs:x2,y1:ys:y2);
dy = y; dx = ones(size(dy));
L = sqrt(1+dy.^2);
dy = dy./L; dx = dx./L;
p1 = [x(:) y(:)];
figure(1); clf;
arrow3(p1,p1+0.001*[dx(:),dy(:)],'r',0.5,2);
hold on
plot(1,2,'b.','Markersize',100)
plot(1,3,'g.','Markersize',100)
h=get(gca,'Children');
set(gca,'Children',flipud(h))

Which arrow3 function are you using?

Hi Orjan,
I understand that you want to bring the blue and green marker on top of the red arrows. To do so you must set the “SortMethod” property of the “axes” from “depth” to “childorder”. This ensures that an object which is near the beginning of the “Children” list always covers an object which is later in the “Children” list.
Here is the updated code:
x1 = 0; x2 = 2; xs = 0.2;
y1 = 0; y2 = 6; ys = 0.5;
[x,y] = meshgrid(x1:xs:x2,y1:ys:y2);
dy = y; dx = ones(size(dy));
L = sqrt(1+dy.^2);
dy = dy./L; dx = dx./L;
p1 = [x(:) y(:)];
figure(1); clf;
arrow3(p1,p1+0.001*[dx(:),dy(:)],'r',0.5,2);
hold on
plot(1,2,'b.','Markersize',100)
plot(1,3,'g.','Markersize',100)
ax = gca;
ax.SortMethod = "childorder";
