Q:

IBM/BlueMix iOT dashboard line graph not using database (only works in realtime)?

(See picture)

I have successfully connected my iOT device to the BlueMix IoT platform
I can see all the events nicely flowing into the dashboard
I now enabled the extension in BlueMix IoT to store all data in "Historical Data Storage" (refer to https://developer.ibm.com/recipes/tutorials/cloudant-nosql-db-as-historian-data-storage-for-ibm-watson-iot-parti/#r_step3)
I can see the data correctly being written in the database
When I put a line graph on the dashboard in BlueMix IoT it does show a graph but only for the realtime data, it seams its not using the historical data now stored in the database. (refer to https://developer.ibm.com/recipes/tutorials/cloudant-nosql-db-as-historian-data-storage-for-ibm-watson-iot-partiii/)

A:

After being in contact with IBM using Skype with screen sharing we found the solution.
Turns out that I did not enter an event in the cards config; I only entered a property and for some reason this is ok for realtime data but not for fetching the historical data out of the DB!
As soon as I entered my event (In my case it was 'status' but this should match your MQTT event name specifically) al worked ok!
