Add a HIGHLOW plot

Something like:

Title '2019 Gasoline Prices'; 
Title2 'New York Vs. Nebraska';
Proc sgplot data=Gas noautolegend; 
band x=month upper= NY_Price lower=0/fillattrs=(color=salmon)
                                     curvelabelupper='NY'; 
series x=month y=NY_Price/ markers markerattrs=(symbol=diamondfilled color=blue)
lineattrs=(color=salmon);                                     
band x=month upper= NE_Price lower=0/fillattrs=(color=cream)
                                     curvelabelupper='NE'; 
series x=month y=NE_Price/ markers markerattrs=(symbol=trianglefilled color=red)
lineattrs=(color=cream);

highlow x=month high=ny_price low=ne_price /
         lineattrs=(color=green);

Yaxis Label="Price of a Gallon of Gas" min=2;
xaxis type=discrete;
format Month monfmt.;

run;
