plot two input of matlab function in simulink

I have two waves as input of matlab function and I want to plot one of them X axis and other one on Y axis , what is the coding i should use ?

I have tried

function out=fcn(acc,slip)

plot(slip,acc)

without any result

Please sketch the desired wave strictly on the X-axis and the other one strictly on the Y-axis.

This helps to visualize what you want to achieve in the final outcome.

You can stick with your custom function for plotting the phase portrait:

function out = fcn(x, y)

plot(x, y)

grid on

xlabel('slip')

ylabel('acc')

end

On the Command Window:

% Either Data is loaded to the Workspace, or generated by some means
t = linspace(0, 10, 1001);
slip = exp(-t).*cos(10*t);
acc = - exp(-t).*(cos(10*t) + 10*sin(10*t));

% Call the function to plot the phase portrait (vector lengths of slip & acc must match!)
fcn(slip, acc)

no actually i dont need to plot(y,x) and there is no formula between two input

@Zainab Alnassar, thanks for being clear on what you really want. A picture is worth a thousand words.

I have edited my Answer to show you how to do it. Hope you find the Answer helpful...

thank you for your help @Sam Chak .

actually these acc and slip are input in simulink as in the picture , they are not equations. I will appreciate your help with that too whereas I need to plot these inputs along with some graphs to compare between them.

I can use XYgraph block but the purpose in comarison .
