How to set date in historical decomposition dynare

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

Please provide the full codes.

I’m sorry for my late reply.

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
