Hi NinaDance
Thanks for posting the thread on our forum.
According to your description, it seems that you want to know if you can change the graph forms of the result.
We did a test in our end, if we add a question as choice, the result will indicate as the bar graph.
If we add question as Likert, the result will indicate as the pie chart.


So if you want to change the graph forms to bar graph, you can click add new>click the drop down menu>Likert>to see the result.

Hope the suggestion will help you.
If my understanding is incorrect, please feel free to post back to tell us your requirement here.
Appreciate your patience and understanding.
Regards,
Stacey
