Can i create a function that will plot more than one figure?

So i want to create a function of the form:

 function isoplot(x,y)
plot(x,y)
end

that will output 5 different figures. At the moment, in my main script I have:

figure (1) %add new plot
plot (final_product_iso(:,1),final_product_iso(:,2)) %plot the molar flow rate of MA at riser outlet vs. values of catalyst re-circulation rate i
title ('Isothermal - Molar Flow of MA vs. Catalyst Re-Circulation Rate')
figure (2) %add new plot 
plot (final_product_iso(:,1),final_product_iso(:,3)) %plot the outlet temperature vs. the catalyst re-circulation rate
title ('Isothermal - Outlet Temperature vs. Catalyst Re-Circulation Rate')
figure (3) %add new figure 
plot (final_product_iso(:,1),final_product_iso(:,4)) %plot butane conversion at the outlet vs. catalyst re-circulation rate
title ('Isothermal - Butane Outlet Conversion vs. Catalyst Re-Circulation Rate')
figure(4) %add new plot
plot (final_product_iso(:,1),final_product_iso(:,5)) %plot MA outlet selectivity vs. catalyst re-circulation rate.
title ('Isothermal - MA Outlet Selectivity vs. Catalyst Re-Circulation Rate')
figure (5) %add new plot 
plot (final_product_iso(:,4),final_product_iso(:,5)) %plot the maleic anhydride selectivity vs. butane conversion.
title ('Isothermal - MA Outlet Selectivity vs. Butane Conversion')

where final_product_iso has already been defined.

How can i put all that into 1 function and call it once?

Thanks

Hello Panagiotis Maximos Sifneos,

You can do it by creating a MATLAB function as described below.

function isoplot(x)
    figure (1) %add new plot
    plot (x(:,1),x(:,2)) %plot the molar flow rate of MA at riser outlet vs. values of catalyst re-circulation rate i
    title ('Isothermal - Molar Flow of MA vs. Catalyst Re-Circulation Rate')
    figure (2) %add new plot 
    plot (x(:,1),x(:,3)) %plot the outlet temperature vs. the catalyst re-circulation rate
    title ('Isothermal - Outlet Temperature vs. Catalyst Re-Circulation Rate')
    figure (3) %add new figure 
    plot (x(:,1),x(:,4)) %plot butane conversion at the outlet vs. catalyst re-circulation rate
    title ('Isothermal - Butane Outlet Conversion vs. Catalyst Re-Circulation Rate')
    figure(4) %add new plot
    plot (x(:,1),x(:,5)) %plot MA outlet selectivity vs. catalyst re-circulation rate.
    title ('Isothermal - MA Outlet Selectivity vs. Catalyst Re-Circulation Rate')
    figure (5) %add new plot 
    plot (x(:,4),x(:,5)) %plot the maleic anhydride selectivity vs. butane conversion.
    title ('Isothermal - MA Outlet Selectivity vs. Butane Conversion')
end

Later you can call the function in the main script with final_product_iso as the argument.

isoplot(final_product_iso)
