Hi @Emun13. I’d say there are at least two possibilities. The simplest one would probably be to create a new version of the tool with two (or more) nodes. For example you could make a “Comparison Graph” tool that has two nodes names “value1” and “value2”. The nodes might not necessarily receive data at the exact same timestamp, but you could plot one line based on the most-recently-received value1 and plot another line based on the most-recently-received value2.
Another option could be to build a new type of node that can receive two values. The Logic Node is just a special node type that was programmed to have some additional capabilities, and you can build new nodes like it. This does require a bit more knowledge of how the edge server works and processes data, but this post could be a starting point: Building new Node types
I’m not sure exactly what you mean by this:
Can you elaborate?
