I want to chart weather predictions, that are obviously in the future. The actual data are in the payload property. I have a property dt where the timestamp (in the future) belonging to these data is. The chart node normally plots the data vs the timestamp of the message. According to the info with Dashboard it should be possible to add a timestamp property to the message and set this to the desired value. I did this but the chart keeps on showing the data vs the timestamp of the message that is fed into the chart node.
Apparently the feature does not work.
Can anyone be of help?
