Predefined Graph function........

Expand Post »
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.

Re: Predefined Graph function........

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

Re: Predefined Graph function........

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.

Re: Predefined Graph function........

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

> gcc.exe -mwindows -o aplot.exe aplot.o -lkoolplot
> -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32 -lstdc++ -lsupc++
What you have are linker error messages.
My guess is you need
-lkoolplot
somewhere.
