Bimalsha,
I did some testing with PLplot last year and was able to get a nice
prototype library put together. The library exposed a small set of PLplot
routines to Chapel.
http://plplot.sourceforge.net/
http://plplot.sourceforge.net/docbook-manual/plplot-html-5.11.1/
PLplot isn't the most aesthetically pleasing plotting library by default.
Some customization would be needed to improve the default experience for
Chapel users.
PLplot offers several rendering options, image export formats, and unicode
support. PLplot is a "tried and true" library in terms of history - it goes
back to 1994. PLplot offers *several* C-interface functions that easily
work in conjunction with Chapel.
If you'd like to see the prototype code, I can post it up on github in a
day or two. Just say the word!
ggplot2 is a library to keep in mind as a gold-standard for plotting data.
ggplot2 is popular in the R, numpy, scipy, and scikit-learn communities.
For R, ggplot2 is the default plotting API.
Due R and scikit-learn's popularity, one could argue that ggplot2 has
become a very familiar API for several developers, scientists,
data-scientists, and statisticians.
http://ggplot2.org
There is a Python implementation of ggplot2 available on github that is
worth studying. Chapel would benefit a great deal from a ggplot2 API. The
Python-ggplot2 implementation would make a great guide for someone learning
Chapel.
https://github.com/yhat/ggplot
As a suggestion, you could build a ggplot2 API in Chapel that uses PLplot
as it's "rendering layer". With the right abstractions, you can make it
easier in the future to swap out the PLplot layer for another, more
sophisticated, rendering library.
Developing a ggplot2 library for Chapel that uses PLplot to render would be
a great initial plotting solution for Chapel.
Here are a couple of other plotting libraries popular in the Python-Pandas
user community which you might also like to review.

Hope this helps!
