### 把matplotlib包裝成獨立視窗
|
||||
```python
|
||||
class Plot2D(Frame):
|
||||
def __init__(self, parent, dataCollector, **kwargs):
|
||||
Frame.__init__(self, parent.mainWindow, **kwargs)
|
||||
|
||||
self.parent = parent
|
||||
self.mainWindows = Toplevel(parent.mainWindow)
|
||||
self.mainWindows.title("AF State")
|
||||
self.figure = plt.Figure(figsize=(9,5), dpi=100)
|
||||
self.figure.suptitle('AF value plot', fontsize=16)
|
||||
self.ax = self.figure.add_subplot(111)
|
||||
self.canvas = FigureCanvasTkAgg(self.figure, master=self.mainWindows)
|
||||
self.canvas.get_tk_widget().pack(fill='both')
|
||||
self.axline = None
|
||||
|
||||
self.dataCollector = dataCollector
|
||||
self.dataCollector.start()
|
||||
|
||||
def close(self):
|
||||
print("Plot2D close")
|
||||
self.mainWindows.destroy()
|
||||
self.dataCollector.stop()
|
||||
self.dataCollector = None
|
||||
|
||||
def draw(self):
|
||||
if self.dataCollector:
|
||||
datax, datay = self.dataCollector.getPlotData()
|
||||
self.ax.clear()
|
||||
self.ax.set_xlabel('Last {} datas'.format(self.dataCollector.getDataLength()))
|
||||
self.axline, = self.ax.plot(datax, datay)
|
||||
self.canvas.draw()
|
||||
|
||||
def getWindow(self):
|
||||
return self.mainWindows
|
||||
|
||||
def getLastData(self):
|
||||
return self.dataCollector.getLastData()
|
||||
```
|
||||
|
||||
其中這一行：
|
||||
```python
|
||||
self.mainWindows = Toplevel(parent.mainWindow)
|
||||
```
|
||||
是用來開一個新的視窗，其中的`parent.mainWindow`就是用`tk.TK()`所產生出來的root。
|
||||
|
||||
因為需要一直更新資料，所以需要的一個`DataCollector`來提供資料，`DataCollector`會提供畫圖需要的list，如：
|
||||
```python
|
||||
datax, datay = self.dataCollector.getPlotData()
|
||||
```
|
||||
|
||||
`DataCollector`的定義如下：
|
||||
```python
|
||||
class AfStateCollector(threading.Thread):
|
||||
def __init__(self, dataLength=100, pollingInterval=0.033):
|
||||
threading.Thread.__init__(self)
|
||||
self.dataLength = dataLength
|
||||
self.pollingInterval = pollingInterval
|
||||
self.stopEvent = threading.Event()
|
||||
self.data = []
|
||||
self.xdata = []
|
||||
|
||||
def run(self):
|
||||
while True:
|
||||
if self.stopEvent.is_set():
|
||||
break
|
||||
|
||||
afValue = self.readAf()
|
||||
self.data.append(afValue)
|
||||
self.xdata.append(len(self.xdata))
|
||||
if len(self.data) > self.dataLength:
|
||||
self.data = self.data[-self.dataLength:]
|
||||
self.xdata = list(range(self.dataLength))
|
||||
|
||||
# print(f'afValue = {afValue}')
|
||||
time.sleep(self.pollingInterval)
|
||||
|
||||
print("AfStateCollector stopped.")
|
||||
|
||||
def readAf(self):
|
||||
ReadTestXUreg_cmd = "lvreg testxu read 10"
|
||||
ReadTestXUreg_cmd_process = subprocess.Popen(ReadTestXUreg_cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
|
||||
|
||||
outstring, err = ReadTestXUreg_cmd_process.communicate()
|
||||
outstring = outstring.strip().decode('utf-8')
|
||||
outstring = int(outstring, 16)
|
||||
outstring_H = (outstring & 0xFF00) / 256
|
||||
outstring_L = outstring & 0xFF
|
||||
outAFStat = int(outstring_L * 256 + outstring_H)
|
||||
|
||||
return outAFStat
|
||||
```
