I have 7 Dashboard 2 graphs getting flow variable data from function nodes. Four of them are working just fine. For some reason the other three will not accept the data. The data is simple 2 or 3 digit numbers in number format not string. Those three graphs work just fine if I send the data with an Inject node but not with a function node. I'm stumped and hoping someone can come up with a fix action.

How do you have the chart nodes set up?  
What does the data look like?

Fed the data into a debug node, show us what you see. Also show us how the chart is setup.

Something is wrong.  
WIthout seeing the data or an export of the chart node it's hard to help you beyond that.

Not correctly you haven't

The dashboard doesn't care how you trigger the data. It is the data that matters in the two cases and probably does not match the chart config in the one case. The data must be different when you trigger it differently. If you had done as we asked we would probably have been able to point out the problem.

Very likely something to do with msg.topic and the Series config in the chart.
