I found some solution which helps to analyze a single graph. Free Open source solutions to analyze a single graph...
JMeter Plugins - look onto custom graphs in this package;
JWeter tool for logs analyzing & visualization
Looking for a solution or open source tool which helps to analyze the JMeter dashboard report which having 23 graphs.
I am not sure to fully understand the question , but I'll try to answer.
Have you generated the HTML report as described here ?
This reports provides the most complete information for analyzing a load test.
Is your question about generating it, in this case I pointed you to the manual.
If not, what is your issue with the HTML report , and why do you write "some of them provide better results reporting out-of-box than JMeter's original ones" ?
Since AFAIK, the HTML report provides the same information with even more graphs and dashboards.
Edit:
Regarding analysis of the report, this does not exist currently and this is usually the role of a performance/load test expert. Maybe in the future through IA, that might exist. So for now, try to understand what each graph provides as information and correlate between them, or ask for assistance of a performance tester.
