I am using rangecolumn chart.The dates on x-axis retrieving from database.Scenerio is that same date has different time slots.in my code whenever a date which has more than one time slot it repeat itslef which is logically wrong.e.g. record (2012-01-01) has two time slots.means i want fix dates on x-axis retrieving from database using ajax call.i am using label parameter because if i use ‘x’ parameter date make itself interval i want fix dates.thanks
