Draw Runtime Graph in Unity3d

Hi,

I am try to get the ECG signals on Unity3d and have been looking on how to draw graphs in unity3d but couldn't find one. The serial data is from Arduino which gets the data from Heart Rate Monitor.

So can anyone help me on how to plot the ECG signals in Unity3D?

some options
- using LineRenderer https://docs.unity3d.com/ScriptReference/LineRenderer.html
- using GL.Lines https://forum.unity.com/threads/drawline-with-gl.235793/ *this would give nice thin sharp lines
- asset store has many line drawing plugins, like https://assetstore.unity.com/packages/tools/particles-effects/vectrosity-82 , oscilloscope seems perfect https://assetstore.unity.com/packages/tools/utilities/monitor-components-23765
- can draw into texture: https://docs.unity3d.com/ScriptReference/Texture2D.SetPixel.html
- using shaders https://www.shadertoy.com/view/4dfBWn
