[Testing Forum]

JMeter version - 2.13

I have following plugins in my JMeter installation - 

And was wanting to generate graphs for a previously run test - 

But I end up with following exception -

Yes you did.

The zip distribution for JMeter plugins has important directory hierarchy inside it. You seems have extracted all files into one directory instead of separate places. Please follow exactly the steps from here: http://jmeter-plugins.org/wiki/PluginInstall/
