arbitrary function plot on Tecplot xy plane
 

Hello

Now i'm trying to plot an equation(y=f(x)) on xy plane with fluent data by tecplot360 to comparing the line by equation and fluent data.

how can i define the equation and plot on xy plane?!

plz help me~

for your understanding i attached some pics

i made a equation with new variable V102, V102=4.73*0.0005*(10**0.3)*(MAX({X}-0.139,0)/0.0005)**0.3

1. I want to overlap the upper and lower. How can I do this?

2. result from the equation contains wrong lines. How can I remove it?
