Hi,

My tags doesn't appear on the "Browse Tags" drop down menu even enable History.

Even after changing the values? Can you browse the database tables themselves to see if any tables have been configured correctly?

Looks like your database, tag provider, tag and Power Chart are correctly configured. You could check the following:

**Confirm tags are being written to the database**  
If you go to Tools -\> Database Query Browser and selected "NewConnection", can you see the tables created by the Historical Tag Provider?

If the tables are there, check whether anything is being written to the data table _ **sql\_data\_1\_YYYY\_MM.** _

**Refresh the tag browser**  
If you have tag data appearing in the database, try refreshing the Power Chart tag browser and see if the tags come up.

**Restart tags**  
In the past, I've had tags not appear until I've restarted them in the designer Tag Browser.

Here you are the solution.

1. Edit Tag propriety to " On change" rather than Tag group first
2. Once tag available on Power chart Tag browser you can change its propriety to "Tag group"  
 ![Sample Mode to On change](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/c/fccab4e639891ea7470557db05fe60c9afa3e86c.png)
