Drag coefficient depend of reynolds number.

Hi everyone, I have a problem drawing, drag coefficient dependence of reynolds number, function. Maybe some ideas?
How to do this graphic?

please give some details about ur method, mesh, geometry, solver etc.

I'm doing this tutorial.
It's very interenting, how to draw a graphic where drag cofficient depends of reynolds number.
Do I need UDF there? Or there is some other ways how to make reynolds number as a variable (From laminar to turbulent fluid).

Any ideas?

Calculate the flow with different inlet velocities and use software like gnuplot, excel or whatever to create the chart?

I'm doing it right now.
But it's realy long work
