Hi dharmendr sir,

I have a dynamic multiple google gantt chart that appear after after putting flight number flight date and flight type. and click on search button gantt chart of all department shown.

my gantt chart shows 24 hours x axis like start from 12 AM, then 2,4, 6, 8, 10.12PM, 2,4, 6, 8, 10,12AM.

I just want to change these 24 hours axis to min and max time from database.

i mean according to putting information of flight date no then with in this data min and max time of time should on x axis not 24 hours time.

i means just want to set min and max axxording to database available min and max time not 24 hours.
