the summary report defaults to pie charts, but I want to see my answer in bar charts. Is there any easy way to change all to bar charts?
Unfortunately there is not an easy way to change one chart type to another. We have to manually change them ourselves – http://help.surveygizmo.com/help/article/link/summary-report#change-chart-type
If you haven’t already responded, SurveyGizmo is currently running their own survey on the Reporting functions. That might be a good opportunity to tell the developers what you need.
