python - Making a plot in a second window using data from main window -
i'm trying make program in have main window , second window. second window should opened checking check-box in main window , closed unchecking it.
the following minimal example works fine (thanks importanceofbeingernest !), want spin arrow (the one, bent when run example) changing spinbox in main window.
solution: see 5th comment in first answer!
import sys pyqt4 import qtgui, qtcore matplotlib import pyplot plt mpl_toolkits.mplot3d import axes3d matplotlib.backends.backend_qt4agg import figurecanvasqtagg figurecanvas matplotlib import animation import numpy np class newsphere(qtgui.qmainwindow): def __init__(self): super(newsphere, self).__init__() self.mainbox = qtgui.qwidget() self.mainbox.setlayout(qtgui.qhboxlayout()) self.setcentralwidget(self.mainbox) self.spin = qtgui.qspinbox() self.spin.setvalue(20) self.spin.setmaximum(100) self.spin.setminimum(-100) self.checkplot = qtgui.qcheckbox("check") self.mainbox.layout().addwidget(self.spin) self.mainbox.layout().addwidget(self.checkplot) self.plot = none self.checkplot.clicked.connect(self.showplot) def showplot(self): if self.plot == none: self.plot = plot(self.kinematic()) self.plot.show() # register signal closure self.plot.signalclose.connect(self.uncheck) # register signal spin value changed self.spin.valuechanged.connect(self.kinematic) else: self.plot.close() self.plot = none def kinematic(self): x = self.spin.value() / 100 v = np.matrix([[1.,x,0.],[0.,1.,0.],[0.,0.,1.]]) 0 = np.matrix([[0.,0.,0.],[0.,0.,0.],[0.,0.,0.]]) pos = np.hstack([v, zero]) return pos def uncheck(self): self.checkplot.setchecked(false) self.plot = none class plot(qtgui.qwidget): signalclose = qtcore.pyqtsignal() def __init__(self, pos=none): super(plot, self).__init__() self.setlayout(qtgui.qhboxlayout()) self.fig = plt.figure() self.ax = self.fig.add_subplot(111,projection = '3d') self.fig.tight_layout() self.ax.view_init(40, 225) ''' dashed coordinate system ''' self.ax.plot([0,1], [0,0], [0,0], label='$x_0$', linestyle="dashed", color="red") self.ax.plot([0,0], [0,-10], [0,0], label='$y_0$', linestyle="dashed", color="green") self.ax.plot([0,0], [0,0], [0,1], label='$z_0$', linestyle="dashed", color="blue") self.ax.set_xlim3d(-3,3) self.ax.set_ylim3d(-3,3) self.ax.set_zlim3d(-3,3) self.canvas = figurecanvas(self.fig) self.layout().addwidget(self.canvas) self.pos = pos self.setup_plot() self.ani = animation.funcanimation(self.fig, self.update_plot, init_func=self.setup_plot, blit=true) def setup_plot(self): self.ax.legend(loc='best') self.position = self.ax.quiver(0, 0, 0, 0, 0, 0, pivot="tail", color="black") return self.position, def update_plot(self, i): x_zero = self.pos[:,3] y_zero = self.pos[:,4] z_zero = self.pos[:,5] v_x = self.pos[0,0:3] v_y = self.pos[1,0:3] v_z = self.pos[2,0:3] self.position = self.ax.quiver(-x_zero, -y_zero, z_zero, -v_x[0,:], v_y[0,:], v_z[0,:], pivot="tail", color="black") self.canvas.draw() return self.position, # need make sure animation stops, when window closed def closeevent(self, event): self.signalclose.emit() self.close() super(plot, self).closeevent(event) def close(self): self.ani.event_source.stop() super(plot, self).close() if __name__ == '__main__': app = qtgui.qapplication(sys.argv) main = newsphere() main.show() sys.exit(app.exec_())
here working example of think trying achieve.
main window has spin box , check box. once checkbox clicked, new window plot show , animation start. current value , array given plot window. if change spin box value while animation running, updated. when plot window closed or when checkbox unchecked, animation stop (and deleted).
