Creating an NPS question with Limesurvey is easy. Use question type array and answer options from 0 to 10.
I have created several NPS surveys with Limesurvey in the past and for one project I also created a special reporting dashboard. Check project #4 ("Interactive dashboard showing statistics and charts based on Limesurvey survey data") at
www.limesurvey-consulting.com/integration/
for more details.
This is how we are presenting the NPS details at that dashboard:
The circle shows the overall score which can range from -100 to +100 and the chart at the bottom show the aanswer distribution.
