Addin data file

i am a student and want to make few graph in which i want to give data through file.
kindly help me.

here is sample

the x and y coordinates i want to give them from file

What you are asking is not a plotly problem. Just parse the file through a file buffer or if you are on nodejs use fs to parse the data and then just plot the file

i actually want to know how please share code or you can make changes to my code
