How to change a variable name in eps file

Stochastic simulations
1

Hi, I am running DSGE model, and designated a variable like below:

var y $y_t$ (long_name='Output gap')
    i $i_t$ (long_name='Nominal interest rate') 
    pi $\pi_t$ (long_name='Inflation rate');

I know that eps files are generated automatically so I got IRF graphes in a folder. However the variable names in the eps files are just alphabets(y,i,pi), not Latex format letters. How can I modify the variable names to the Latex format?

Are you using Dynare 4.6.3?
