I know that you can create dashboards in a separate tab using node-red-dashboard . However is it possible to have actual visualizations in the admin editor itself? For example might it be possible for part of the DAG to include a chart of the output of a node of some kind, right there in the editor? …

There are very few graphical elements for the editor, but see node-red-contrib-data-view (node) - Node-RED to include a chart in the editor. It's still in development, but does provide a basic chart.

This is brilliant! So it's proof of concept that you can go "off the reservation" with the design of in-editor nodes. Not that I necessarily want to pollute the editor with all sorts of gumpf, but intermediate visualization of data is really quite a cool use case. And if this is possible, other thin…

That is just awesome. I'm so excited about Node-red. I had looked at it a few years ago but let it lapse and picked up again because I need a system for financial markets data flows. The only concern I still have is Node-Red's throughput capacity for "firehose" data (say, 300 data points per second)…

[image] vegabook: but I assume there are back-pressure capabilities that will allow me to downsample if necessary. Yes, but as node-RED is only single threaded, it may be an advantage to downsample the data in a script (not in node-RED), and then use the downsampled data in node-RED to proces…

agreed. There will be a downsampling capability in the datafeed service external to Node-Red (written in Elixir calling Rust for heavy workloads).

I also find node.status extremely useful to display data beneath the function & debug nodes.
