kid-axis-coordinates in mother-axis problem

What is a "mother axis" and "kid axis"? Do you mean an uipanel and an axes object? Maybe the code of https://www.mathworks.com/help/matlab/ref/getpixelposition.html helps you:

Hi Jan:

Thanks for your reply. there are some problem with my license server so I can only explain it without figure now. below are the steps:

plot a random figure:

    x=rand(50,1);
    y=rand(50,1);
    scatter(x,y)
    axis off
    axis equal
    set(gcf,'color','w')

the axis you see in the figure is referred as 'mother-axis'

2. in the figure panel, use the zoom in, to zoom in to any axis,, the result axis is referred as 'kid-axis'

3. I plot a box in the kid-axis and get the coordinate using command:

    k = waitforbuttonpress;
    rect_pos = rbbox;

the rect-pos is the position in kid-axis.

what I want is its position in mother-axis.

hope this demonstrate my problem clearly.

Thanks!

Yu

Sorry, I still don't get it. After axis off I do not "see an axis in the figure". Do you mean the axes object?

"use the zoom in, to zoom in to any axis,, the result axis is referred as 'kid-axis'" - again: when I zoom in and out, I still have the same axes object and I'm not sure, what the "kid-axis" is.
