Looks like you asked the plotting question here. Not sure why you chose to ask part of the question on MSE and part of it here.

Anyway, the code I provided in addition to the answer from MSE is enough for you to put together a working solution. Try it.

The reason for the Export is to generate a self-contained example for you to experiment with. If you evaluate the code provided and follow the steps, you will see that a plot is generated.

If no plot is generated with your CSV file then it may not be in a form that can directly be plotted. You have provided no details on the format of your CSV file, does it have a header row, how many columns, which columns need to be plotted, are the columns strings that need to be converted to numbers, .....???

Before trying to do anything in the cloud, make sure the code works locally first. What is the result of evaluating

data = Import["path to your file", "CSV"]

Hey Rohit,

Thanks.

I am a bit confused, and I apologize for simple questions here, it has just been a week since I started using Mathematica.

I don't need to export any data, so I've just removed the 'Export' function.

The FormFunction allows the file to be uploaded. Once uploaded, is there any way I can visualize the contents of the file on the screen? The plot isn't showing any data right now visualizing the format will probably give me an idea of what needs to be done.

Thanks again! Siddharth
