Translate a plot across its axes

Hi guys,

I'm writing a program which draws the hysteresis loops on a stress/strain plot. In order to do this, I need to be able to move successive plots so that they begin where the last plot ends.

As you can see in the picture, I want to translate the steep-looking curve across the figure so that its head matches with the top of the shallower curve.

Thanks in advance,

Can you resize your image, it's too big.

Try this demo:

% Make curve 1
x1 = 0:25;
y1 = x1 .^4;
% Make curve 2
x2 = 0:50;
y2 = 40000 * x2 .^ 0.3;
% Plot them
plot(x1, y1, 'r-', 'LineWidth', 2);
hold on;
grid on;
plot(x2, y2, 'g-', 'LineWidth', 2);

% Now make new, shifted curve
y3 = y1 - y1(end )+ y2(end);
x3 = x1 - x1(end) + x2(end);
% Plot the shifted curve.
plot(x3, y3, 'b-', 'LineWidth', 2);

legend('Curve 1', 'Curve 2', 'Shifted Curve 2');

If values are (x,y1) and (x,y2) then

plot(x,y1,[x+x(end)-x(1)],[y2+y1(end)-y1(1)])
