Hello I have problems showing the graphics that are made with the net promotor score option. The graphs shown through the option Community Surveys Consolidated Report module on the site are empty and those shown in the report from the administrator the graph is displayed, but when printed it is blank.
I attached a link so they can check. Thank you
