Dear all

I have seen in a few papers in macroeconomics (which is not my field of expertise), histograms showing results for "the distribution of the impact effect" of impulses after plotting the OIRFs.

​​​​​​I want to have a histogram that shows the distributions of the impact effects and another histogram showing the distribution of the one-period effect based on 1000 draws from the posterior distributions generated by estimating the VAR. (For each draw from the parameter space, I should draw 1000 candidate shocks).
My Var and OIRFs are below

Code:
var macro news output   , lags(1/2) dfk lutstat 
irf create order1, step(10) set(myirf1, replace) 
irf cgraph (order1 macro ouput oirf), level(90)​​​​​​


Can anyone help with this, please?
Thank you
