Because this thread is nearly the only one I found while searching the web I will post my improved solution of every... here:

everyNth(countColumn,labelColumnNum,N) =((int(column(countColumn)) % N == 0) ? stringcolumn(labelColumnNum) : "");

and you have to use it this way:

plot ... u 1:xtic(everyNth($2,2,10))
