Thank you firstly.

My equation likes following format:

aX^2+bXY+cY^2+D=0

Do you have some idea to plot it in an excel chart?

Thanks

You can calculate slope, intercept, and correlation coefficient from
worksheet data using SLOPE, INTERCEPT, and CORREL worksheet functions, or
compute more statistics using LINEST.
