From where you click you mean:
  • cut the elements after the one you click on with respect to the x-axis?
  • cut the elements after the one you click on with respect to the position of the element in the original array?
Have you looked into ginput?

As Sara suggests, using ginput to let the user select a x-value from which to crop:
clear
clc
x = 1:10*pi;
figure
subplot(2,1,1)
plot(x,sin(x));
title('Original plot');
uiwait(msgbox('Select an x-value from which to crop','modal'));
[x_user ~] = ginput(1); % Let the user select an x-value from which to crop.
x(x>x_user) = [];
subplot(2,1,2);
plot(x,sin(x));
title('New plot with cropped values');
xlim([min(x(:)) max(x(:))]);
results in the following:
