I want to put quarterly dates starting in 200Q2 on horizontal axis of graphs of my shock decompositions?  
How could I do this?

ts = dseries(‘fsdat\_simul.m’);

data(series=ts, first\_obs=1950Q3, last\_obs=2000Q3);

disp(‘First date is $1950Q3’)

This doesn’t work

Dear @jpfeifer , I fixed the previous problem.  
But I want to do the same thing with smoothed shocks. Is it possible?

I would recommend you simply construct the graph from the output in `oo_.SmoothedShocks`

go to C:\dynare\4.5.7\matlab, open plot\_shock\_decomposition.m, In line 82 replace

initial\_date = dates(‘1Y’) with for example initial\_date = dates(‘2004’); and keep your .mod file and

modified plot\_shock\_decomposition.m file in the same directory (folder)
