How can I fix this problem (with the Chart component)

I am a beginner and am using this program for a school assignment where I have to track daily water intake. I have made a graph and put in the code shown in the image so that when a button is clicked it adds to the graph.


However when I use the AI Companion on my phone the graph is not showing up and the image below shows what the issue is.

Does anybody know how I can fix this issue.

You are trying to use the AI2 Charts component on iOS.

According to https://doesappinventorrunonios.com/
it is not yet implemented on iOS.

Either do your testing in Android, or find a different charting alternative from

Chart support on iOS is available on TestFlight currently and will be out later this year on the App Store.
