How to plot data from different files in same plot/figure

I have different matlab files running in the same script, and I want to plot data from these different files in the same plot. Currently, I am using if´s and elseif´s but this is giving me a plot per data file. How can I plot all these in the same plot/figure?

if k==1
plot(ENGINE_SPEED.time,RPM)

    elseif k==2
    plot(ENGINE_SPEED.time,RPM)

    elseif k==3
    plot(ENGINE_SPEED.time,RPM)
end

Thanks.

doc plot

The first argument to plot can be an axes handle. Always use this

e.g.

hFig = figure; hAxes = axes( hFig );

plot( hAxes,...)
