[Gretl-users] Plot of residuals from Engle-Granger Cointegration Regression #2

I managed to create a plot of the cointegration regression using the functionality to define a new variable which I specify as uhat = parameters of ordinary least squares regression and then plot those with the 1.5x standard deviation. See chart below I do this using console command... gnuplot uhat sdm sdp --with-lines --time-series my QUESTION: how can I change this command to tell gnuplot to create and plot all 3 variables on 1 axis and have same axis on left and right??
