SEMILOG HELP

[Tim Rohrer]

Hello all,

I just subscribed to this group so hopefully I'm actually on it.  I was 
told it succeeded.

My question is with semilogy.  I'm trying to get the following values to 
graph.  I have the first column stored in a vectored called xval and the 
second in yval.  The command I issues is:  semilogy(xval,yval).  The 
error I get is:

octave:3> 
gnuplot> pl "/tmp/oct-02853aaa" t "line 1"
                                          ^
         line 0: x range is invalid

Here are the values (there are 91 rows):

    0.00000  -15.00000

I was able to take this problem and properly graph in using matlab.  Any 
ideas on the problem?

Thanks,
