我刚开始使用PyQt,这是我的第一个GUI应用程序。尝试在迭代中显示图表旁边的表格时遇到了挑战。请在下面找到我的代码:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
%matplotlib qt5
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar
from matplotlib.figure import Figure
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(QtWidgets.QWidget):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.gridLayout = QtWidgets.QGridLayout(self.centralwidget)
self.gridLayout.setObjectName("gridLayout")
self.scrollArea = QtWidgets.QScrollArea(self.centralwidget)
self.scrollArea.setWidgetResizable(True)
self.scrollArea.setObjectName("scrollArea")
self.scrollAreaWidgetContents = QtWidgets.QWidget()
self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0, 780, 533))
self.scrollAreaWidgetContents.setObjectName("scrollAreaWidgetContents")
self.gridLayout_2 = QtWidgets.QGridLayout(self.scrollAreaWidgetContents)
self.gridLayout_2.setContentsMargins(0, 0, 0, 0)
self.gridLayout_2.setObjectName("gridLayout_2")
self.scene = QtWidgets.QGraphicsScene(self)
self.graphicsView = QtWidgets.QGraphicsView(self.scrollAreaWidgetContents)
self.graphicsView.setObjectName("graphicsView")
self.graphicsView.setScene(self.scene)
self.gridLayout_2.addWidget(self.graphicsView, 0, 0, 1, 1)
self.figure = Figure()
self.canvas = FigureCanvas(self.figure)
self.scene.addWidget(self.canvas)
self.pushButton = QtWidgets.QPushButton(self.scrollAreaWidgetContents)
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.vis_plot)
self.gridLayout_2.addWidget(self.pushButton, 1, 0, 1, 1)
self.scrollArea.setWidget(self.scrollAreaWidgetContents)
self.gridLayout.addWidget(self.scrollArea, 0, 0, 1, 1)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 25))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "PushButton"))
def vis_plot(self):
df = pd.DataFrame(np.random.randn(100,4),columns = list('ABCD'))
ax1 = self.figure.add_subplot(1,2,1)
ax2 = self.figure.add_subplot(1,2,2)
for column in df:
col = pd.DataFrame(df[column])
col.plot.hist(ax=ax1, title=str(column))
col_stat = col.apply([np.min, np.max, np.mean, np.median])
col_table = col_stat.rename(index={'amin':'Minimum', 'amax':'Maximum','mean':'Mean', 'median':'Median'})
col_table.reset_index(level=0, inplace=True)
col_tablerender = col_table.rename(columns={col_table.columns[0]:'Metric', col_table.columns[1]:'Value'})
ax2.table(cellText = col_tablerender.values,
colWidths=[0.25]*len(df[column]),
colLabels=col_tablerender.columns,
cellLoc='center',
loc='left',
bbox=[-1,0.7,.6,.3])
self.canvas.draw()
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
这是我目前得到的:
我目前拥有的
如果表格未绘制但打印在对应图的旁边,我希望如下图所示:
