Now-a-days, different types of graphs are presented in the journal of International repute. These graphical presentation of data is not possible using MS Excel.
So kindly suggest some free software for creation of good quality of graph.
I would recommend R / Rstudio with ggplot2 package. It requires some basic programming skills, but what you gain is versatile tool for almost any graph you could imagine.
Oh, excellent question! Matlab, Grapher, Wolfram, free analogues of MSOffice like OpenOffice... Ask Google, it will provide plenty of options... Good software for brilliant (but quite simple) graphs is a Numbers in the MacOS
Thanks to all the researchers for giving there valuable suggestions.
But, still my question is partially answered, because I am interested to know about the free software. Most of the software comes in the discussion, like MATLAB, Sigma, R or GG Plot is the paid software.
If you are looking for opensource: Python, ROOT could be one option. Else you can use MATLAB if you have a subscription. Saving in .eps format would preserve the quality.
