使用AxesSubplot对象（matplotlib＆tkinter）在曲线下添加颜色

Question

I'm using matplotlib module in order to draw graph in tkinter window. I'm using AxesSubplot object to configure the graph's style.

My question is: How do I draw color under the curve of the graph, with this object (AxesSubPlot object)? This is the code that I use to configure and draw the graph:

def graph_handle(self):

    canvas = matplotlib.backends.backend_tkagg.FigureCanvasTkAgg(self.__fig, master=self.__SettingsFrame)
    canvas.show()
    canvas.get_tk_widget().pack(side=BOTTOM, fill=BOTH, expand=True)

    self.__axes = self.__fig.add_subplot(1,1,1,axisbg='#221E1E')
    self.__axes.plot([0])
    self.__axes.spines['bottom'].set_color('black')
    self.__axes.spines['top'].set_color('white')
    self.__axes.spines['left'].set_color('#221E1E')
    self.__axes.spines['right'].set_color('#221E1E')
    self.__axes.xaxis.label.set_color('#221E1E')
    self.__axes.tick_params(axis='x', colors='black')
    self.__axes.tick_params(axis='y', colors='#221E1E')

    self.__fig.gca().clear()
    self.__fig.gca().plot([0], [0])
    self.__fig.canvas.draw()

Of course I have the tkinter settings in the code and other stuff, If you think it's relevant, write this down in the comments and i'll add.

Thanks.

Edit: So far, the code provides this graph: And I want to add color under the curve (Between the curve and the down axis)(Sorry for the bad drawing, it's just a demonstration):

Edit2:

This is the function that I call whenever the array to plot is updated(ie, when I need to update the graph, because there are more values in the array to plot then before):

def update_plot(self, txnamount):

    self.__GraphPlot[0].append(self.__TransactionsCurrently)
    self.__GraphPlot[1].append(self.__WalletBalance+txnamount)

    self.__axes.fill_between(self.__GraphPlot[0], self.__GraphPlot[1], facecolor="yellow")

    self.__fig.gca().clear()
    self.__fig.gca().plot(self.__GraphPlot[0], self.__GraphPlot[1], color="white", linewidth=0.8)
    self.__fig.canvas.draw()

You need to use Axes.fill_between . There is a nice example on the matplotlib page .

In this case you'd use

self.__axes.fill_between(x,y, facecolor='yellow')

where x and y are the array to plot.
