Live analog plotting - python

[Prabhakar Ray]

Hi Guys,

I'm reading a continuous analog value using python and plotting it using drawnow(). Since the plot is moving it's getting difficult to note down the coordinates of any specific point. I intend to implement a moving data cursor which can follow the graph and can give me real time coordinates of the point without the need of clicking or hovering over a point.

can anyone help me with this ?
