Build ID: I20070323-1616 Steps To Reproduce: 1. New a Tube chart. 2. Flip axis. 3. Preview the chart in viewer. Expected behavior: - The bottom of each series should be arc. - The top of each series should be oval. Actual behavior: - The bottom and top of each series are direct line, refer to attached output file. More information:
