Hello.
I've gone over your posting and I understand the requirement. There are several plotting programs such as gnuplot, eplot, bashplotlib, etc. that can be used to take data from a bash script and generate a plot.
My name is Ravi Damarla and I'm a senior developer located in India. I have more than 10 years of experience of working with and administering Linux and its variants.
I'm also well versed with Bash scripting, Perl and Python.
I think that I have the necessary expertise to work on your project and will be able to do a good job.
Looking forward to hearing from you.
Thanks,
Ravi
