Refresh data after publishing dashboard

Hello,

I'm new to the community. I hope i will be able to learn Power BI without asking to much help from community :catlol:

I made a dashboard using AZURE COMSUMPTING INSIGHT (online service) to get date.

All data has been downloaded and then i have been able to design a new dashboard. This is, show the daily consumption of a department group by kind of service. I had to create a new column to achieve this (like example below)

As you can see, the data are shown until june 17, the day i created the dashboard.

I published the dashboard online, thinking it will update data value, but no...

How could i do to have data refreshed automatically every day?

A Microsoft colleague tells me to generate an app from the dashboard, but no success

thanks for you support
