What's that? Could you provide an example of reverse plotting or reverse function?

Hi Chubeka,
If you want to reverse a function you may use flip function:
x = linspace(0,10);
y = sin(x);
x = flip(x); % reverse the values of x
plot(x,y)
If you want to reverse the axes then here is an example code which you may use:
ax = gca;
axes(ax)
x = linspace(0,10);
y = sin(x);
plot(x,y)
ax.YDir = 'reverse'; % for reversing the Y direction
ax.XDir = 'reverse'; % for reversing the X direction

The reverse command was very helpful for me. All I wanted was for my plot to start from the higher values to lower values but I was stuck trying to solve this issue for the x axis in an FTIR plot.
Thank you! @Shubham Rawat
