task interval date too small, doesn't visualize

Gantt
#1

Hi if task interval date too small, doesn’t visualize 16-apr-2015 to 30-apr-2015 doens’t visualize,
but if interval it’s > 1 month it visualizes.
Is there an option to tell to show every task that will last less than 1 month?
thanks

It seems such tasks should be shown by default. See example: docs.dhtmlx.com/gantt/snippet/fedcfcd5
