Topic: problems with large text file

Hey,

I would like to import a text file with about 20 columns with more than 300k lines.
Importing text files works fine till a size of about 20 columns with 250k lines, but if there are more than about 250k lines the program shows an ERROR called: "external exception EEFFACE".
My text file looks like this:
x    y    y    y    y    y    y    y    y    y    y    y  ...
1    0    -0.99060    0.04290    0.20670    -0.98670    0.02340    0.10920    0.95550    -0.06240    -0.40560    0.24960  ...
2    0    -0.98670    0.03900    0.20280    -0.98280    0.01950    0.10920    0.95940    -0.06630    -0.40560    0.24960  ...
3    5    -0.98670    0.04290    0.19500    -0.98280    0.01950    0.12480    0.96330    -0.06240    -0.40560    0.24570  ...

5    3    -0.99060    0.04680    0.21060    -0.98670    0.03120    0.10920    0.96720    -0.06240    -0.40170    0.24960  ...
       ...
       ...
       ...
Is there any chance to import such large text files?

I'm using Windows XP with 2gb RAM.
I would be really happy if there is a chance to solve my problem :-)


Thank you, Tobi

Re: problems with large text file

I will take a look at it and see what I can do. However I never thought anyone would try to import such a huge file and it is not trivial to handle so much data. However I can at least fix the not very informative error message.

Re: problems with large text file

I have done some optimizations in the import handling so it now can handle 300,000 lines. But it is really pushing Graph to the limit. You can find it in the beta version at
