import sys pyqt5 import qtwidgets  matplotlib.backends.backend_qt5agg import figurecanvasqtagg figurecanvas matplotlib.backends.backend_qt5 import navigationtoolbar2qt navigationtoolbar import matplotlib.pyplot plt  import matplotlib.finance mpf  class window(qtwidgets.qdialog):   def __init__(self,data,parent=none):     super().__init__(parent)      self.candledata=data[0]     self.plots=len(data)     if self.plots>1:         self.linedata=data[1]      self.figure = plt.figure(figsize=(30,18))     self.axes = self.figure.add_subplot(111)     self.axes.hold(true)     self.canvas = figurecanvas(self.figure)      self.toolbar = navigationtoolbar(self.canvas, self)     self.toolbar.hide()      self.button2 = qtwidgets.qpushbutton('zoom')     self.button2.clicked.connect(self.zoom)      self.button3 = qtwidgets.qpushbutton('pan')     self.button3.clicked.connect(self.pan)      self.button4 = qtwidgets.qpushbutton('home')     self.button4.clicked.connect(self.home)       layout = qtwidgets.qvboxlayout()     layout.addwidget(self.toolbar)     layout.addwidget(self.canvas)      btnlayout = qtwidgets.qhboxlayout()     btnlayout.addwidget(self.button2)     btnlayout.addwidget(self.button3)     btnlayout.addwidget(self.button4)     qw = qtwidgets.qwidget(self)     qw.setlayout(btnlayout)     layout.addwidget(qw)             self.setlayout(layout)  def home(self):     self.toolbar.home() def zoom(self):     self.toolbar.zoom() def pan(self):     self.toolbar.pan()          def plot(self):     [obj.insert(0,i) i,obj in enumerate(self.candledata)]     mpf.candlestick_ohlc(self.axes,self.candledata,width=0.8,colorup='r',colordown='g')     self.axes.grid()     print(self.plots)     if self.plots>1:         in range(len(self.linedata)):             self.axes.plot(self.linedata[i][0],self.linedata[i][1],color=self.linedata[i][2])     self.canvas.draw()

now plot figure , zoom in small part blow:

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
