I read this series fdate in xlsread:
[x,fdate,raw] = xlsread('C:/Users/Owner/Documents/Research/Data/USTreasury/Z1_FL210/z1_csv_files/csv/Z210finaccts.xlsx','A27:J305');. I define fdate1 = fdate(:,1) and get the following column vector:
{'1951:Q4'}
{'1952:Q1'}
{'1952:Q2'}
{'1952:Q3'}
{'1952:Q4'}
{'1953:Q1'}
{'1953:Q2'}
{'1953:Q3'}
{'1953:Q4'}
{'1954:Q1'}
{'1954:Q2'}
{'1954:Q3'}
{'1954:Q4'}
{'1955:Q1'}
{'1955:Q2'}
datetick('x', 'YYYY:QQ','keepticks')
How can I use/transform this column vectors to plot on the x axis in this line of code:
plot (fdate1,x(:,3:4),'LineWidth',1) %1951Q4
I get 'Error using plot Invalid data argument'
Thank you

I'd recommend converting your fdate cell array to an array of datetimes:
fdate = datetime(fdate, 'InputFormat', 'uuuu:''Q''Q');
From there, you should be able to plot as needed.
