Crystal Report – Gantt Chart for Daily Meeting Schedule

Well I’m looking for help! about Crystal Gantt chart. The problem is that Crystal report is not showing activity on hourly basis.

It requires

Each record field i.e. Date in my datbase
&
Two Values fields i.e. Start Time, End Time (HH:MM AM/PM)

does someone know how to show meeting start and end with rectangle block and showing time gridline with regular gaps of 30minutes!

It looks like crystal only show gantt chart with activities span over few days?
