How to change the origin axes in an image

17 views (last 30 days)
I tried with this:
ax = gca;
ax.Visible = 'On';
set(ax, 'YTickLabel', get(ax, 'YTick')+ py1 + em1/equiv + e/2/equiv);
set(ax, 'XTickLabel', get(ax, 'XTick') + px1+((lm/2)/equiv));
I want to get the blue axes from the red, but when i execute the program it appears: Invalid or deleted object, reffering to ax.
I want to plot some data respect from the blue exes.

It’s my understanding that you are trying to change the origin axes in an image. Following is the code for the same:-
I = imread('cameraman.tif');
shiftX = -200;
shiftY = -150;
imshow(I,'Xdata',[1 size(I,1)]+shiftX,'Ydata',[1 size(I,2)]+shiftY)
ax = gca;
ax.Visible = 'On';
hold on
% Indication that the origin has shifted.
plot(0, 0, 'r+', 'MarkerSize', 30, 'LineWidth', 2)
hold off
For more information refer to imshow.
