[Orca-users] Re: Data not showing up on graph

[Jeff Brickley]

I actually sent you the wrong copy of the input file.  The data is between 0 and 10.
The format is exactly as I sent before. The only difference is that instead of number between 72 and
287 the numbers are .4, .6, .8 etc.
Any other ideas?
