I have 1000 files corresponding different time steps, can be opened by notepad++ containing 6 columns and I would like to plot 2 first columns as X & Y for watching the changes through the time. Each of the columns has been separated with space. Or, generally speaking, how to plot files using. I have done it by python but in terms of visualizing, I guess #paraview works better.
Should be opened in ParaView as a time series. Just make sure they are named, data_0.txt, data_1.txt…
I know, but the problem is that I do not know how to exclude 2 first columns while all files have 6 columns.
No idea what you mean and why you would not want to read the first 2 columns.
because each datafram has 6 columns but I need to plot just 2 first columns
Still not sure to follow, but to me it looks like you can just open your file in ParaView and then plot them into ParaView.
Please share a file example if you need further help.

I have attached a piece of results and as you can see it has 6 columns, how can I have the changes 2 first columns through the time
just open your file with ParaView and plot it into the line chart view.
I think what @mwestphal is suggesting is that you let ParaView read in all 6 columns and then plot just 2. The csv/text file reader is not capable of selecting which columns to read (it always reads all of them). But all the plotting tools allow you to select what variables get plotted.
