As a newbie I've gone throught many example and I'm still coming up short.
I'm extracting date and temperature (later humidity and BarrPress) into a 3 line chart using ui.

The sql will provide hourly readings of temperature however, the chart is blank.
The input to the chart:
0/29/2024, 4:13:13 PMnode: debug output from chartSELECT DateAndTime, Temperature FROM weather_1 GROUP BY DATE(DateAndTime), HOUR(DateAndTime) order by DateAndTime DESC LIMIT 10 : msg.payload : array[10]
array[10]
0: object
DateAndTime: "2024-10-29T16:07:05.000Z"
Temperature: 87.6
1: object
DateAndTime: "2024-10-29T15:07:03.000Z"
Temperature: 87.19
2: object
DateAndTime: "2024-10-29T14:07:04.000Z"
Temperature: 87.12
etc,etc,etc
Any help would be appreciated.
Thanks.
