How to make a smooth graph?

Hi, I have this data with me.

   P_load = [0,8000,10000,11000,20000,25000,25000,21000,30000,20000,12000,45000, 12000,45000,23300,12000,15000,17000,20000,16000,12200,1000,2000,100];% Watts

so how can I make it smoother?. I nearly damage my brain now.

Help appreciated.

   P_load = [0,8000,10000,11000,20000,25000,25000,21000,30000,20000,12000,45000, 12000,45000,23300,12000,15000,17000,20000,16000,12200,1000,2000,100];% Watts
   x=1:numel(P_load)

   xx=linspace(1,numel(x),1000)

   yy=interp1(x,P_load,xx,'spline')

   plot(x,P_load,'or',xx,yy,'-m')
