Question: How to make a graph from data consisting of 1000 lines in a .txt file?

hello,

I have a .txt file with 1000 lines of data.

This data was collected from an electronic compass located in a car moving in different directions.

Each line was written in function of time,every 0.1s.

Each line has 4 columns, and each column represents a cardinal point.

1st column--->North, 2nd column--->East, 3rd Column South---> 4th column West

768------768------768------2

768------768------768------2…

768---------2------768---768…

768---------2------768---768…

768---------2-------2-----768

768---------2-------2-----768…

When there is a low number, it means that the compas is moving in that direction. So, the first two lines, it is moving westwards, the next two lines is moving eastwards and the last two ones south-eastwards.

How can I graph the trajectory of the car? Or at least to make some kind of graphic?

Thanks.
