The first column is always blank

I notice that the first column in the Gantt chart is always blank. For example in the following sample: the data range is from 2018-04-01 to 2018-04-11. The Gantt chart displays an empty column for 2018-03-31. Is there any way to prevent this column from showing? In other words, can 2018-04-01 display as the first column?

If there is no specified date range, Gantt shows +1 cell at the left and right side of the chart so it will be possible to create links from the most left and right tasks. If you don’t want that, you can set the date range or global start_date and end_date parameters of the chart:
Please note, that the tasks outside the date range won’t be displayed.

Thank you. This resolved my issue.
