Unable to show current date or user input date Gantt Chart

Hi,
I have been using the gantt chart and I have the issue showing the current date or user input date in timeline. I have passed the date parameter [startDateField] through object to gantchart. Despite the correct format and correct date, gantt charts appear to be empty. While duration and start field is accepted by gant.

A snapshot:
<ganttChart id=“ganttChart”
additionalSegmentFields=“taskName”
balloonDateFormat=“JJ:NN”
brightnessStep=“10”
categoryField=“taskName”
colorField=“color”
columnWidth=“0.5”
dataContainer="??"
durationField=“duration”
height=“100%”
marginRight=“70”
period=“HOURS”
rotate=“true”
segmentsField="??"
startDateField=“2016-01-01”
startField=“start”
theme=“LIGHT”
width="100%>

Any help or response would be appreciated.
Thanks,

Any help here please?
