I have generated a graph using matplot by importing data from my .csv file. Now I want to append that graph into the same .csv file. I am using python 3. Can anyone guide me how to do this?
A csv file is a text file. It consists of comma separated values. It cannot contain images.

I'm doing the QGIS 3.22 Beginner’s Guide on youtube.
Getting stuck trying to import the CSV data file.
The tutorials says to go to Data Source Manager > Delimited Text > File Format, then select Regular Expression delimiter.
The issue I have is that the CSV delimited file I created in Excel, automatically selects the CSV option but I need the delimiter option.
NB - when saving the file in Excel, I selected File > Save As > CSV (Comma delimited) as instructed.
But in QGIS, when I import and select Regular Expression delimiter, it doesn't take the commas into account, i.e. it shows one column instead of four columns.
The sample CSV file is over here. https://drive.google.com/drive/folders/1_g10p7qL4nDBX1HmbD2RBtDS-m6wIfc6

Any thoughts on how to get the delimited file to import correctly?
Thanks
How can i use jupyter lab to read and extract tables from pdf files
A typical pdf file with text tilles subtitles and tables in between. I need the coding to extract the table under a specific title, and cleaning some unwanted text like page numbers
What are some of the coding to do that ?
Tabula-py: you can parse a PDF and convert it into a CSV, TSV, JSON, or a pandas DataFrame.
I´m struggling to open a text file using pandas.
I have this dataset from an experiment and it should be a 87x249 table.
However, when I use the pandas df.read_csv() command I get all the time a table which is 87x1. I tried to change the delimiters but I always get different tables of 87x1.
I tried to open the ascii file in excel and then save it as a csv. Then it worked and I got a nice table. But the point for me is to use the txt file directly.
I have fits file containing numerical values of magnitudes of star clusters. I need to see them as a csv file. Any code to run in python to do the trick?
Note: Fits file is not an image file, it is a table file.
why not use fdump ?
fdump -- Convert the contents of a FITS table to ASCII format.

Using the Paraview application, I would like to extract data from a .vtk unstructured grid file and convert this data into .txt or .csv files. In the file menu, I have tested Save Data but I obtain a .csv file with one column "Cell Type" containing only the value 9. How can I get the data in a .txt or .csv file ? My .vtk file contains 9 variables and for each variable, I have data at each time step.
Looks like your dataset contains only PointsData, not CellData. Make sure to Select :
"Point Association : Point"
when saving the data as a .csv file.
