How do I display lines over points in biplot?
显示 更早的评论
Hi everyone,
I am creating a couple of biplots from the outputs of the "pca" function. The "biplot" function seems to have a couple of bugs, unless there are parameters I can call to adjust them.
What I am most concerned about is my point cloud displaying on top of my lines, as you see below, as a fourth variable is completely obscured:
The alignment of the PC2 axis label is also irritating, but I can live with it if there's nothing I can do about it. Mostly I need to know if the points-over-lines thing is a bug, or a feature I can flip.
Thanks for any insight!

If the figure object that you wish to move to the top (or bottom) of the figure has a common property, you could use the uistack function to set that object's property. E.g., if you want to move the red dots to the bottom of your biplot, you could do this:
redMarker = findobj(gcf,'Color', [1,0,0]);
uistack(redMarker,'bottom');
Similarly, you could grab hold of any object and move it anywhere using 'uistack'.

Try This
chH = get(gca,'Children')
set(gca,'Children',[chH(end:-1:1)])
