i am working on my project which is on regeression of lines .
well i have been successful in fitting a straight line to the given set of coordinates . since i have come so far after a lot of striving , i have been a bit exhausted on writing a graphic function of plotting the co - ordinates and displaying a graph.

Well is there any function or header file which will directly plot a graph if i provide a given set of co - ordinates.

Short answer - no.
Longer answer - depends on which OS/Compiler you have and what libraries you have installed (or willing to install)

well i am willing to install any libraries.. n working on minGW compiler.
n working on windows , its kinda not possible to change the platform .. but in the worst case that can be considered.....

Would 80x25 on a terminal be good enough resolution?

Graphics of any kind come with baggage. There is no "Just draw a line".

Actually, that's not entirely true.
If you want to use your browser to do some of the work, then outputting a simple SVG file could do the job.

dude i think you havent undestood me .......
i just need some simple fuction which will plot the graph for me when i inout the co ordinates, thats all . there is no complication in it.

i got a link and copied those libraries , but its giving me an error.

the underneath is the link from where i copied libraries
http://codecutter.org/tools/koolplot/

the error i got is something like this

graph.cpp||undefined reference to `Plotdata::Plotdata(double, double)'|
graph.cpp||undefined reference to `plot(Plotdata const&, Plotdata const&)'|
graph.cpp||undefined reference to `COLOR'|

Thanks for the link, could be useful for others wanting to convert 'up' to the modern world.

Did you know that before my last reply?
Cos playing guessing games sucks.

What you have are linker error messages.
My guess is you need
-lkoolplot
somewhere.
