I need read the data array from the *.txt file. then use this data to draw a
graphic with x, y axles in a form. The x, y axles scale need to be labeled as
number.
The form can be resized and the graphic and axles will be enlarged or
shrinked as the scale.
Can anybody give me a hand?
Thanks

i do think you need a commercial package. This won't be easy!

You could use the Crystal Report that comes with the Visual Studio .NET. It
will be fairly easy if you get experience with Crystal Report. I can finish it
in 1-2 hour using C#.
There are also other report tools or pure .NET tools, mostly are commercial,
some are free.

get a book on GDI+, walk through a few examples and
you should be able to draw some graphics on a form.
pay attention to these topics: coordinate systems, translation
between different coordinate systems and transformation.
and look for materials covering graphics optimization
techiniques to reduce flickering when resizing forms,
including the so-called double buffering, etc...
