Check which items are enabled for display on your chart by tapping the three dots top right in your chart screen then 'Manage items' in the drop-down:
If you're not seeing all items that you'd like to display on your chart in the 'Display on chart' tab then toggle over to the 'Items to track' tab and make sure that the items are enabled there.
Items must first be enabled in 'Items to track' in order to be available for 'Display on chart'
Please note that if you have individual custom info lines set to display on your chart then they will only display once they have at least one day of data entered for them that menstrual cycle. This is to ensure an uncluttered chart view!
