Fiori freestyle Chart

[glauco]

Hi.

I followed an example, but the app is not showing my chart.

https://blogs.sap.com/2019/10/14/simple-sapui5-app-to-display-charts/comment-page-1/#comment-610585

Project shows no errors.
My cds view return records.
My test in /iwfnd/maint_service returns records and metadata.
Created freestyle app and pointed to my CDS view service.

How to make it appear on page please ?
What could I forget to do ?
