I've succeded in solving the problem that seems due to usage of show. Both of the function i called had a show function enabled that seems to confuse a bit the behaviour of matplotlib. so I commented in both function show and only put it in the module that called both function. Not to comfortable if you have to call a lot of function that use show command but it worked :)
