BI desktop is line but BI in web just is one point

[Tanbui]

Anybody can help me solve my problem with BI, 
I design my dashboard ("Area chart" type) by BI desktop and this shows line. But when i publish and see it in BI web (app.powerbi.com), this is a point only.
How can I see the line in BI web?
Tks for your kindly help!

Hi @Tanbui 
I think you have to drill down on your date hierarchy.Sometimes it happends when there is only 1 year available.

You can fix it on power bi service as well.

If my post helps Please give kudos and accept as solution!
