Thank you for your post.
At this time, FileMaker Go does not support charting. For a listing of differences, please see Knowledge Base Article #7733:
If you don't need the chart to be dynamic (responsive to changes in found set and sort order), you could use regular filemaker to copy and paste the chart image into a container field so that GO users can see the chart.
That's a limited fix at best, but it may serve as a work around in some cases.
Got it, thanks
