I have some text files in a folder. I generated a graph from those textfiles which has some shapes. I attached the graph. I want to know which textfiles are refered to round shapes in the graph and then I would like to know the radius and area of that round shapes. Can anyone help me with this? Thanks.
Assuming you are looping through text files, fetching data and plotting them, I would suggest adding legends to the axes to distinguish plots from different files(data). Here is the detailed documentation of adding legents while plotting different data.
To find area under plot, you can try usingtrapz function.
