Have you looked at my suggestion in your previous topic? Rather than printing the raw output to stdout, print the output as json string. Every time you print a line, it gets added to the `msg.payload` coming out of your pythonshell node. Meaning that in order to use it you have to split lines first, then parse the context. If instead you were to format your **entire** output to a python dictionary, then call json.dumps on it and print that, you can convert that single string to an object back in node-red through the JSON node. You can then use regular nodes to get the different outputs out and plot them to a chart, see the link in Paul’s message for that.  
But keep in mind for that to work, you have to deliver properly formatted input first.

Context for others reading this:
