I would like to build, for the survey I am working on, a graph linked to a limesurvey equation to show as the final output of the survey showing the respondent the score obtained in the questionnaire. The idea would be to build a speedometer from 0 to 199 (maximum value of the equation), with a "stick" indicating the exact value obtained by the respondent.
From what I've seen so far it seems that this can't be done in the final message of the survey (correct me if I'm wrong), but it seems it's possible to do it on a landing page by building the graph in php; what we don't get is how to transfer the value obtained by the respondent, calculated through the equation question, from the survey to this landing page.
