Hi Thomas,

thank you for answerring. I have already developed further. Here is my
current code.

def PlotFrame(self):

    self.fig = Figure (figsize=(5,4), dpi=100)
    self.ax = self.fig.add_subplot(111)
    self.ax = self.fig.add_subplot(111) #fuer 2d-Plot
    self.ax.set_title('Definition der LRUGL')
    self.ax.set_xlabel('Fahrzeugbreite y [mm]')
    self.ax.set_ylabel('Fahrzeughoehe z [mm]')
    self.ax.axis([-2000,2000,0, 5000])
    self.ax.grid(True)

    self.canvas = FigureCanvasTkAgg(self.fig,self)
    self.toolbar = NavigationToolbar2TkAgg(self.canvas,self)
    self.toolbar.update()
    self.plot_widget = self.canvas.get_tk_widget()
    self.plot_widget.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
    self.toolbar.pack(side=tk.BOTTOM, fill=tk.BOTH, expand=1)

    self.ax.plot(np.zeros(100))

    def onMouseMove(event):

        self.ax.lines = [self.ax.lines[0]]
        if event.xdata and event.ydata: # python3 often has None
            self.ax.axhline(y=event.ydata, color="k") #(y=event.ydata,
color="k")
            self.ax.axvline(x=event.xdata, color="k") #(x=event.xdata,
color="k")
        self.canvas.show()

    self.canvas.mpl_connect('motion_notify_event', onMouseMove)
    self.canvas.show()

    def fig_ax_request():
        publish('FIG,AX',self.fig,self.ax)

    subscribe('REQUEST_FIG,AX',fig_ax_request)


def DrawPlot(self):

    def test_plot():

self.ax.imshow(np.random.normal(0.,1.,size=[1000,1000]),cmap="hot",aspect="auto")
        self.fig.canvas.draw()

    self.buttonAAA['command'] = test_plot

    def get_fig_ax(fig,ax):
        self.fig = fig
        self.ax = ax

    subscribe('FIG,AX',get_fig_ax)
    publish('REQUEST_FIG,AX')


Now i have a table for input and an embedded diagram in tkinter canvas.
This code above is only for testing. I want the functionality that i can
write values in the table and let it simultanously paint into
matplot-Canvas. Hav eyou some suggestion or imrpovements to do that ?


 Best regards from Stefan
