I am trying to use a line chart in the custom widgets. I can send data via MQTT.fx to gauge widgets just fine but when I try to send data to a line graph I keep seeing “no data available for this period”. I am using the same topic string as when I send data to a standard widget and I can get widgets to automatically pop up with my data but I get nothing with the line graph.
The topic string: v1/“MQTT Username”/things/“Client ID”/data/1
Of course the MQTT Username & Client ID are those provided in my device information screen.
The data I am publishing is: flow,m=22.3
Also I do not get the live selection for the time frame. The graph is set up to pick up data from channel 1, the time frame is for today
