I stored the data from PMU by openHistorian.
I deleted the device and create the device again in openHistorian manager.
Then I cannot see the trend of the previous data on a web application.
I think the reason is I created a new database when I create the device again.
The archive(d2 file) is still in the Archive folder.
How to import the previous archive to openHistorian?
I’d like to see the trend and download csv file.
