yeah… i had this workaround in my mind… but actually i am fetching data from database so it is such that:-
there are centers and there are courses…. now, some centers may not have all the courses and i want to plot the enrollments…
so.. it would’ve been easier if i could give custom string values to “x” attribute directly and then it would group them together according to that :(
Anyways… i’ll go for the workaround.. thanx
