Most likely it is because data view is not being refreshed and the chart is working because chart has a refresh interval after which it will fetch latest data.
To refresh the data view where you placed a table to show values, you should have a timer microflow that retrieves an object of your data view entity and just call a “refresh in client” on it. This microflow will run every x seconds, so you will see your table getting updated values at the set interval. Set the timer interval same as your chart interval.
Refresh in client
P.S: In MindSphere default Asset Management Connector, you have non persistent entities. So to retrieve data from non persistent entities, one option could be to associate it with currentSession. Then you can access it via system variable $currentSession available in microflows. If you are storing data, then simple retrieve from database would work as described above
