Hello,

If I copy your "small", I don't have any problem... 
Maybe your vec is interpreted as text?
Try 

ListPlot[ToExpression[small]]

Hope it helps!

 Hi,

I have a hard time trying to understand why I get the floating-point error
in this
particular case: I dont't see what's wrong with the list I am trying to
plot.
Here it is:


In[1]:=  small=Take[vec,2]

Out[1]:=  { {30.06, 23523}, {56. 38,00005}}

In[2]:=  ListPlot[small]

Then I get the error message:

Graphics::gptn : Coordinate 30.06 in {30.06, 23523} is not a floating-point
number.

Hope someone can explain this to me.

Best regards,

Henning Heiberg-Andersen
