Configuring the Simple Dashboard

The dashboard you see should look something like this From the selector in the top left next to Site ID select the id of the site you'd like to view the data for. If you see no ids either you have not run any sites on the accompanying instance or you have not configured the historian correctly.

Selecting the Time Range

After selecting your site it is likely that you will still not see anything on the graph. This is because datapoints are plotted according to the time in the site. So if your site starts in the year 2020 you will need to select that time range. You do this by selecting the drop down in the top right and selecting the correct time period for your site.

Success!

At this point you should see some timeseries data coming from your site.
