Hello all,
I am trying to use the recessionplot to shade recessions on my plot. My date series is just the years from 1970 to 2018. Do I need to convert the dates even though they are just numbers to use the recessionplot?
Here is the code I am using:
clear; clc
load('GrowthAccountingVectors.mat')
plot(Year,normalAtothepower)
recessionplot
hold on
plot(Year,normalKoverYtothepower)
plot(Year,normalLoverN)
plot(Year,normalYoverN)
hold off
legend("A ^ (1/(1-alpha))", "(K/Y) ^ (alpha/(1-alpha))","L/N","Y/N")
xlabel("Year")
ylabel("Normalized Values")
title("Growth Accounting for Spain")
grid on
Thank you in advance!

Hi Hussain,
For overlaying recession bands on plot using ‘recesssionplot’, date information needs to be converted to serial date numbers. Date information can be converted to serial date numbers by using ‘datenum’.
Below mentioned link would help you understand how to convert dates using ‘datenum’:
