From the help info. `Multiple series can be shown on the same chart by using a different msg.topic value on each input message.`
So each line will; nedd its own msg.topic value.

Are you trying to fill a chart with historical data or add real time data? If you are filling with historical data then you need to put everything into one message. There is a link in the help text for the the chart which tells you the format needed.
Edit, back at my computer now, the link is [node-red-dashboard/Charts.md at master · node-red/node-red-dashboard · GitHub](https://github.com/node-red/node-red-dashboard/blob/master/Charts.md)

Thanks for the info, it works now. I ad a function Node to each output of my Influx Nodes. And then connect them all to one Chart Node.
Function Node Line1
msg.topic = "Line 1"
return msg;
Function Node Line 2
msg.topic = "Line 2"
return msg;
