I am using a slightly modified version of node-red in something called LoopEdge/LoopFlows but I believe it works in the same way as usual node-red.
I have a bar chart and I was wondering, is there any way I could order the bars so they appear in the same order each time? (D20...D24)
This is my flow right now:
At the moment, the bars on the chart appear as each device connects, which happens in a random order... I'm not sure if regular node-red has the green nodes, but after they connect, they pass JSON to my function, which extracts values as msg.payload and msg.topic, and sends it to the chart.
I'm not sure if this is even possible to do because of the way the data appears.
Sorry if this is difficult to understand. I'm not very knowledgeable about node-red... can anybody tell me what might be a solution?
