Hello there. I have managed to implement my own plug in controller for the JMeter. Everything works fine so far (or at least it seems so) and I get no errors on my MSDOS console. The problem is that the JMeter does produce a graphical representation of the data. For example if I choose the "Spine Curve" visualizer I always get the message "Waiting for samples" even though the JMeter shows that my controller is running (the red dots above are constantly green - actually I am not quite sure if they should be constantly green or keep changing from red-green-red all the time). My customized controller is written on the same manner as the jdbc controller but I cannot seem to find anywhere in the jdbc controller any references to the visualizers classes. I guess they are invoked through some other classes but I do not know which ones? Any help is deeply appreciated.
Thank you.
Panos
