Superimposing a line plot onto a contour plot using data from excel

I have a data sheel in excel, with a contour plot that outputs an Outlet Temperature of Harvested Milk in a Heat Exchanger as a function of Mass Flow Rate of Cooling Water and Number of Cows.

I also have a line plot of the Minimum Cooling Water Flow Rate to Output Milk at 13C as a Water Flow Rate vs Number of Cows graph.

I would like to import the Contour Plot Data and Line Plot Data from excel to Matlab, then plot the contour plot and superpose the line graph onto the contour plot as an isocontour.

I've attached images for clarity hopefully.

Anybody would need data to do much...attach the .xls file or read it and attach a .mat file

I've attached the excel file.

A = xlsread("Contour.xlsx") ; 
x = A(1,2:end) ; 
y = A(2:end,1) ; 
Z = A(2:end,2:end) ; 

contourf(x,y,Z)
