That's 3 pythons in 1 request. Why not just use python? pandas.read_csv()

https://pandas.pydata.org/docs/reference/api/pandas.read_csv.html

then use the plot() method

https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.plot.html

Wow, look at that, no Labview involved.

Hello,

Yeah I know how to do it with Python.

I am just trying to learn how to use LabView and integrate with python..

ok I see, you need to use a python node, have you tried that? 

[wzh0053@auburn.edu]

Yes I am trying to use the python node. 

As far as I know, I can read the csv file using this Read Delimited. However, I don't know how I can use its output to use as input to Python node. Sorry, I am a very newbie to Labview..

Try something like this, you will need to add some things to this, like your paths, to make it work but its a starting point

Thank you so much!

I was trying to find this symbol, but I couldn't find same one.

I believe it is the array subset. How can I build that one?

Thank you again

Right click on the orange wire and then navigate as shown here:

That icon is actually the Index Array function that changes its image to match the array wired into it and is expandable for multiple outputs.  Just hover over the bottom edge to expand it.
