Re: [Gnuplot-py-users] gnuplot-py 1.7 and gnuplot 3.8 mouse-interaction conflict

[Nadav H. <na...@vi...>]

I tried again, but now it seems that the mouse command don t pass 
through to gnuplot --- no coordinates display, no zoom etc. Switching 
back and forth between 1.6 and 1.7 reveal that it is 1.7 problem only.
