Gruff expects an Array of values to graph.  It looks like you might be  
feeding it an Array of Arrays and even those values look fishy.

I recommend simplifying the problem.  First, try just reading the  
first five lines of your data file and graphing just that.

When you have that working, you can expand the data and see how things  
go.
