交互式QDialog显示Matplotlib图
我有一个python（2.7）程序（myGraph.py），该程序使用matplotlib通过showGraph（）函数创建图形。
现在从QDialog中，我正在调用此函数showGraph（）以将图形显示如下：
import myGraph
# ...
# ....
class myTable(QDialog):
# ...
# ...
myGraph.showGraph(graphName)
与“ graphName”相关的图形正确显示，但几乎QDialog（myTable）再次出现在图形上方，并且我无法仔细检查该图形，例如展开和滚动它。为此，我必须关闭不需要的QDialog（myTable）。因为，我必须看到从QDialog中选择的不同图传递不同的graphName。
因此，基本上，我希望从QDialog中选择一个“ graphName”并调用我的matplotlib程序来查看图形，并对其进行仔细检查。在此期间，我的QDialog应该位于图形后面。关闭图后，QDialog应该会重新出现，然后从对话框中选择一个新的“ graphName”并对其进行仔细检查，依此类推。
程序的框架依次如下：
============ 1。 Analyser.py ==============================
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QMessageBox
from PyQt5 import uic
from PyQt5.QtCore import QCoreApplication
Ui_MainWindwo, QtBaseClass = uic.loadUiType('analyser.ui')

self.ui.setupUi(self)
self.ui.alertPushButton.clicked.connect(self.createAlerts)
:
: ## different other signal-slot connections etc.

def createAlerts(self):
:
: ##Building up of a list 'alrtLst'
: ##for example final alrtLst is:

['Graph2', 'Sales4-8', 'KNT', '500'],
['Graph3', 'Sales9-10', 'MT', '400'],
['Graph4', 'Sales11-12', 'TSL', '500']]
from alertTable import AlertTable

app = QCoreApplcation.instance()
if app is None:
app = QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
============= 2。 alertTable.py ==============================
from PyQt5.QtWidgets import QDialog, QTableWidgetItem
from PyQt5 import uic
import myGraph ##myGraph.py program
class AlertTable(QDialog):
def __init__(self, alrtLst):
super(AlertTable, self).__init__()

self.tableWidget.setHorizontalHeaderLabels(header_labels)
for row in alrtLst:

self.tableWidget.insertRow(inx)
self.tableWidget.setItem(inx,0,QTableWidgetItem(str(row[0])))
self.tableWidget.setItem(inx,1,QTableWidgetItem(str(row[1])))
self.tableWidget.setItem(inx,2,QTableWidgetItem(str(row[2])))
self.tableWidget.setItem(inx,3,QTableWidgetItem(str(row[3])))
def tableClick(self):
row = self.tableWidget.currentItem().row()
cell = self.tableWidget.item(row, 0),text()
myGraph.showGraph(cell)
============= 3。 myGraph.py ==============================
import matplotlib.pyplot as plt
def showGraph(grphName):
dfc = pd.read_csv('E:\\analyzedFiles\\'+grphName+'.csv')
:
: ##Construct graph

plt.show()
