I have a plot where I set the axes positions explicity. My code for this is:
ax_left = gca;
ax_left.Position = [0.05 0.05 0.89 0.85];
I'm creating annotations that I'm trying to define locations for explicity. My code for definining the locations for the annotations is:
AxesHandle = findobj(gca,'Type','axes');
plot_proto_wse_hawser_trans.x_min = AxesHandle.Position(1);
plot_proto_wse_hawser_trans.y_min = AxesHandle.Position(2);
plot_proto_wse_hawser_trans.x_max = AxesHandle.Position(1) + AxesHandle.Position(3);
plot_proto_wse_hawser_trans.y_max = AxesHandle.Position(2) + AxesHandle.Position(4);
When I create the annotations, The locations use the ax_left.Position values instead of the AxesHandle Position values. Can someone tell me how to reference the AxesHandle Position values?

The way you've written the code, plot_proto_wse_hawser_trans uses the Poisition values from AxesHandle. You didn't include the annotation code, but the positions you've captured are indeed the x,y or the lower left corner and upper right corner of AxesHandle.
However, AxesHandle is the current axes. There's no difference between:
ax = gca;
and
ax = findobj(gca,'Type','axes');
They both return the current axes. findobj looks at an object and all its descendents to a specified type, but you've pointed it at gca, so it's an exact match.
Maybe you could expand on which axes you're trying to find?

Thank you for the information, Dave B!
I looked through my code and noticed that after I used ax_left.Position, I added things to the plot that adjusted where the axes are located. Those changed were throwing me off. I moved ax_left.Position, and now everything is working.
Thank you!
