How to add a line plot to existing contour plot?
 

Hi,

I already have a vorticity contour plot for flow over an airfoil. I have a (tecfile.dat) generated from other code which has the (x,y) location of the boundary layer (BL) edge around the airfoil.
I'd like to plot the BL edge over the vorticity contour. I am able to load tecfile.dat after plotting the contour and I also see under "Data Set Info" that the new variables (x,y) have loaded under a new Zone.
Can someone please tell how to plot this over the contour? I have tried multiple options in "Zone style" but could not get the BL edge plot over vorticity contour?
