Comment (by iwakeh):

 For avoiding the 500 server error when trying to access the png (as
 reported in detail in #25468) an empty graph/png stating 'no data
 available for this parameter choice' should be generated.  Currently, the
 corresponding csv only contains the header.  Maybe, also add a comment
 here too in case no data is available.  It should be avoided to call R if
 there is no data available.
