Hi, I am looking for solution where I can create a line chart , audio waveforms on node-red defining x axis(voltage) and Y -axis(current). Any ways that I can make use of dashboard board chart for this?

Couple of example's to explore [image] Dashboard tips. ui_chart with linear x-axis Dashboard A little example about ui_chart advanced configuration. Catch the Boson stuck_out_tongue boom [image] [{"id":"1076704a.386908","type":"ui_button","z":"7ee51301.a9185c","name…

Yes you can use non time series format e.g [{ "series": ["X" ], "data": [ [5,6,9,10] ], "labels": [ 24, 25, 23, 26 ] }] where labels is the voltages and data the current more info here about formats, also in the help text https://github.com/node-red/node-red-dashboard/blob/master/Cha…

Just to check: You are displaying an audio wave on a chart and want x to be the voltage? So the wave is vertical on the screen? Usually they are done horizontally. Just checking.

[image] Trying_to_learn: You are displaying an audio wave on a chart and want x to be the voltage? It is charting current against voltage. The usual way of displaying that is to have volts on the x axis and current on the y, which is the stated requirement here.

Hi, I am plotting voltage vs current waveform where I want to fetch real time data from serial input. plot the line chart. I am actually looking for a line where my real-time data is plotted on. **[ { "id": "c6d1832664c2174f", "type": "function", "z": "b1d2a17489d1cb3e"…

Slightly confused can you show an example of what the chart must look like, a sketch on a paper will do then post an image. Also examples of incoming messages would help.
