Question

我有一些问题，第一个问题是我无法更新y轴的绘图限制，第二个是我希望每个传感器看到6条线，正如你在图片中看到的那样我只看到一条如果我做了一些更改，我会在一行中看到所有传感器的变化

这是我创建情节的代码和照片：

# Flag variables
self.isLogging = False

# Create data buffers
self.N = 70
self.n = range(self.N)
self.M = 6 # just one lead - i.e. 1 number per sample
self.x = 0 * numpy.ones(self.N, numpy.int)

# Data logging file
self.f = 0

# Create plot area and axes
self.x_max = 500
self.x_min = 330
self.fig = Figure(facecolor='#e4e4e4')
self.canvas = FigureCanvasWxAgg(self, -1, self.fig)
self.canvas.SetPosition((330,50))
self.canvas.SetSize((550,280))
self.ax = self.fig.add_axes([0.08,0.1,0.86,0.8])
self.ax.autoscale(False)
self.ax.set_xlim(0, self.N - 1)
self.ax.set_ylim(self.x_min, self.x_max)
self.ax.plot(self.n,self.x)

# Filter taps
self.taps = [0, 0, 0]

# Create timer to read incoming data and scroll plot
self.timer = wx.Timer(self)
self.Bind(wx.EVT_TIMER, self.GetSample, self.timer)

这是我抓取数据的地方，我尝试更新情节的限制

    if len(sample_string) != 6:

        sample_string = sample_string[0:-1]
        self.taps[1:3] = self.taps[0:2]
        self.taps[0] = int(array[1])
        #value = 0.5 * self.taps[0] + 0.5 * self.taps[2]
        value = self.taps[0]
        self.x[0:self.N-1] = self.x[1:]
        self.x[self.N-1] = value
        # print sample to data logging file
        if self.f != 0:
            self.f.write(str(value))
            self.f.write("\n")

        # update plot limits
        maxval = max(self.x[:])
        minval = min(self.x[:])
        self.x_max += ((maxval + 10) - self.x_max) / 100.0
        self.x_min -= (self.x_min - (minval - 10)) / 100.0

    # Update plot
    self.ax.cla()
    self.ax.autoscale(False)
    self.ax.set_xlim(0, self.N - 1)
    self.ax.set_ylim(self.x_min, self.x_max)
    self.ax.plot(self.n, self.x)
    self.canvas.draw() 

    if b7 == True:
        self.textctrl0.Clear()
        self.textctrl0.AppendText(array[1])
        self.textctrl1.Clear()
        self.textctrl1.AppendText(array[2])
        self.textctrl2.Clear()
        self.textctrl2.AppendText(array[3])   
        self.textctrl3.Clear()
        self.textctrl3.AppendText(array[4])
        self.textctrl4.Clear()
        self.textctrl4.AppendText(array[5])
        self.textctrl5.Clear()
        self.textctrl5.AppendText(array[6])
        b7=False

p.s我删除了我试图添加其他传感器的错误代码，这里只是一个传感器图的工作代码..

Python更新绘图中的绘图限制和多行
