How to make gantt chat time range bigger

I have make a gantt chat to show the expected start end date, but found that the time range section narrow, how can I make it look more good?

Hi @Miki_Lai ,
Unfortunately, the Gantt chart day range cannot be changed.
I will add the improvement idea in the eazyBI backlog, but cannot promise any development regarding it.

best,
