Unable to Generate Graphs in Non-Gui mode Null Pointer Exception

[dhananj...@8x8.com]

Hi All,

I am using jmeter version - 3.0 r1743807 on CentOS version - CentOS Linux release 7.3.1611 (Core) and java - version "1.7.0_121".

I installed all the required plugins and tried to generate multiple graphs using the jp@gc - Graphs Generator, but I get the below error in jmeter logs.

Jmeter log:
