GDevelop data analytics tool

I have used GDevelop to create data analytics plotter. Please support by watching.

Original usage of GDevelop!
One question please: which solution did you use for the 2 différents datas? (text files, etc.)

Thanks by advance for your response.

I entered each values in variables. But a advanced user can find a easier way.
I have to do only feeding work, then just run and record.
