I am very new to the node-red world. I want to create a graph between two real time variables. I do not want time axis. In place of time axis I want to use real time data from the sensor. For example pressure vs Temperature Graph.
If you send a single point at a time it is assumed to be time based. You can instead send a complete array of points - this is usually used to preload / reload the graph... but can be used to do and x/y plot instead.
if a send a complete array of points then it will no longer a real time data. I want to take take the data from the sensor and directly plot
take a look in the flows library - I put a sample in there -
EXAMPLE: How to create a Bubble chart (can be used as basis for scatter plot too) one of the graphs updates with dynamic data. It might give you some ideas.
Can you please show me how Can I do in x/y plot
