Hi @Bhavnachinnam, welcome to the CHT! The CHT app does not currently provide a growth chart for infants. To clarify your request:
Are you interested in a reference guideline chart, similar to this example from the WHO below? (captured from the WHO site)
Or are you looking for functionality in the CHT application that compares an infants growth data to that of other babies of the same age?
Please feel free to add detail, images, or correct me if I am misunderstanding your request
