I need the above graph as it is. Have a good day.

@KitonumI receive like this

@Christopher2222  yes exactly what you say, velocity and temperature fields. 

@acer Sorry, I have no idea what u are asking, anyway Thanks for your cooperation. have a good day.

@acer Here U and W both are velocities. y is the eta (eg problem). Here want to plot U wrt y
