Hi Jason,
From my testing, the default Chart starts displaying 'No Opportunitities to Show' once an Opportunity Stage is greater than or equal to 29 characters (spaces included).
You have a few options:
1) Decrease the Opportunity Stage name less than 29, you can open the screen: 'New / Edit Opportunity Stages' and adjust the Opportunity Stage name > Save > Refresh the Opportunity Charts to and verify it's loading.
2) Open the Report: 'CRM_Dashboard_Opportunities_CloseRatio' in the Report Designer and increase the size of the chart, which will allow more characters. You can do that by heading over to:
(1) Switch to the Report Explorer (2) Select the Chart object (3) Adjust the size
From my testing only the Width needed to be adjusted to display more than 29 characters in the chart.
Let me know if that works for you.
