I'm trying out the gantt chart type to show sprint schedules. However it doesn't seem designed to show single day events. There are very few settings for this chart type. Am I missing something?
I believe the solution is to push your end date field forward 1 day. The card displays from 12AM start date to 12AM end date. For example if your event date is 2015-03-07, making the end date 2015-03-08 will show the event on 2015-03-07 on your card. Please let me know if there are any questions.
Thanks
