python - 将绘图嵌入 GUI 中

Question

我找到了一个网站 scikit-rf

http://scikit-rf.readthedocs.io/en/latest/tutorials/plotting.html

可以通过以下代码创建史密斯图

ntwk = rf.Network("my data path")
ntwk.plot_s_smith()

然后我想将它嵌入到我的 python gui 中。

import sys
from PyQt4 import QtGui,QtCore
import matplotlib
import matplotlib.figure
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar
import skrf as rf
import numpy as np
class PrettyWidget(QtGui.QMainWindow):

    def __init__(self):
        super(PrettyWidget, self).__init__()
        self.setGeometry(100,100,1200,700)
        self.center()
        self.setWindowTitle('NRW')



        self.initUI()

    def initUI(self):

        grid = QtGui.QGridLayout()
        self.setLayout(grid)
        self.figure = matplotlib.figure.Figure()
        self.canvas = FigureCanvas(self.figure)
        self.toolbar = NavigationToolbar(self.canvas, self)
        grid.addWidget(self.canvas, 3,0,2,12)

    def plot1(self):

        self.figure.clf()
        self.figure.tight_layout()
        self.canvas.draw()



if __name__ == '__main__':  
    app = QtGui.QApplication(sys.argv)
    app.aboutToQuit.connect(app.deleteLater)
    GUI = PrettyWidget()
    GUI.show()
    app.exec_()

但我不知道如何放置或修改下面的代码

ntwk = rf.Network("my data path")
ntwk.plot_s_smith() 

有人可以告诉我你是否有 iedas 吗？谢谢!

Network.plot_s_smith有一个 ax 关键字来在现有的 Axes 对象上绘制。所以你可以像这样修改你的绘图函数:

def plot1(self):

    self.figure.clf()
    ntwk = rf.Network("my data path")
    ntwk.plot_s_smith(ax=self.figure.gca()) 
    self.figure.tight_layout()
    self.canvas.draw()
