Baby Tracker

I’m a child doc. And I need to track my patient’s child growing on my website.
I have a plugin idea like that. Mothers(my patients) registering my website and they create a child profile. After that, they enter their child’s weight,height and head measure for controlling their child growing is normal.

Maybe graph view will be good. For example Normal value draw a line. X axis is month and y axis is weight of child. Mother enter the form her child’s weight, and graph show his child’s weight for compare normal value. Height and head measure works same way.

Is there any idea about that or plugin for solving this issue ?

Best Regards…
