Simulink Multiple output plot on a single graph simulating at different step

Please, I am very new to Simulink/Matlab platform. I have a model designed in Simulink. I am trying to generate a single graph that will show the output of varying the step function. Attached is the model. The commandline below only show for each output. plot(dp.signals(1).values(:,1),dp.signals(1).values(:,2));

Thanks for your prompt response
