Dear Commcare,
We have to monitor the height and weight of the children and track the growth curve. In this regard, how to configure the WHO standard chart with commcare?
You can store the WHO chart data as a lookup table in your app. See more information about that here:

You might be interested in this page on calculating a z-score. It also includes an example table you can upload to your project for this purpose:
