Displaying data plots from workspace when simulation starts

Hi,

I am plotting graphs from simulink model saved to workspace and datas from a matlab code on the same graph. I use 'sim' command to start simulation of the simulink model and i need to display the graphs right after the simulation starts. I use refreshdata and drawnow commands but it only work for the matlab code:but the data from the simulink waits till the simulaton end. Is there any way to display simulink plot when simulation starts?

Thank you!
