Limitation in Nutrition Analysis using z score

Dear DHIS2 Community,

We are using the dhis2 in Tracking children under 2 data to monitor child growth and we are using the Tracker to collect these individual data and their visit on monthly basis to the Health facility. This is towards monitoring children nutrition status.

Looking at DHIS2, the analysis part does not satisfy the nutrition analysis as we need to use z score etc etc. Another difficult part get the file that shows children by number of visit.

Did anyone tried this?
