Can anyone tell me what these scan graphs mean?

Hi everyone, I had my 20 week scan a couple of days ago. I found the graphs tucked in my notes. The sonographer said she couldn't see any issues, but didn't refer to these. Does anyone know which parts of the anatomy they refer to and what they mean? Is it the baby is somewhere between large and small or something else?

Your plotted points are on the middle line so that means your baby is average which is great!

One will be head circumference, one abdominal circumference and one length (I think).
All are on the middle line pretty much so all bang on average. Nothing to worry about.

Thank you so, so much!

Head, abdomine and femur (thigh). They are just checking the baby is growing ok.
