Hi everybody, I'm trying to plot the price of an option against time to expiration time in days (in positive integer ofc). But I need to reverse the time. More specifically, I have 15 daily prices so what I did was building a vector from 0 to 15 and use flipr to reverse the order of my raw vector but it doesn't work because also the price of the option was reversed.
Exp = [0:15]; %days to expiration
P = rand(1,15); %fake daily prices
plot(Exp,P) %is all reversed not just the days to expiration
I also tried with set Xdir as follows
Exp = [0:15]; %days to expiration
P = rand(1,15); %fake daily prices
plot(Exp,P)
set(gca, 'Xdir', 'reverse') %again is all reversed not just the days to expiration
Does anyone have a solution to this issue?
Thanks a lot in advace,
Best,
Marco.

Something like this @Marco Piazza?
Exp = 0:15; % Days to expiration
P = linspace(10, 30, length(Exp)); % Fake daily prices increasing
y=plot(Exp,P, 'b.-');
ax=xticklabels;
xticklabels(flip(ax))

Building on @Image Analyst's comment, reversing the x-tick labels
Exp = 0:15; % Days to expiration
P = linspace(10, 30, length(Exp)); % Fake daily prices increasing
y=plot(Exp,P, 'b.-');
ax=xticklabels;
xticklabels(flip(ax))
