def __drawChart(self): ##绘制图表
self.chart.removeAllSeries() #删除所有序列

## 1. 创建蜡烛图
seriesCandle = QCandlestickSeries()
seriesCandle.setName("蜡烛图")
seriesCandle.setIncreasingColor(Qt.red) #暴涨
seriesCandle.setDecreasingColor(Qt.darkGreen) #暴跌
visible = self.ui.chkBox_Outline.isChecked()

seriesCandle.attachAxis(self.__axisX)
seriesCandle.attachAxis(self.__axisY)
seriesCandle.clicked.connect(self.do_candleClicked)
seriesCandle.hovered.connect(self.do_candleHovered)
## 2. 创建MA曲线
pen = QPen()
pen.setWidth(2)
seriesMA1 = QLineSeries() #不能使用QSplineSeries
seriesMA1.setName("MA5")
pen.setColor(Qt.magenta)
seriesMA1.setPen(pen)
self.chart.addSeries(seriesMA1)

seriesMA1.attachAxis(self.__axisY)

pen.setColor(Qt.yellow)
seriesMA2.setPen(pen)
self.chart.addSeries(seriesMA2)
seriesMA2.attachAxis(self.__axisX)
seriesMA2.attachAxis(self.__axisY)
seriesMA3 = QLineSeries()
seriesMA3.setName("MA20")
pen.setColor(Qt.cyan)
seriesMA3.setPen(pen)
self.chart.addSeries(seriesMA3)
seriesMA3.attachAxis(self.__axisX)
seriesMA3.attachAxis(self.__axisY)
seriesMA4 = QLineSeries()
seriesMA4.setName("MA60")
pen.setColor(Qt.green) #green
seriesMA4.setPen(pen)
self.chart.addSeries(seriesMA4)
seriesMA4.attachAxis(self.__axisX)
seriesMA4.attachAxis(self.__axisY)
## 3. 填充数据到序列
dataRowCount = self.itemModel.rowCount() #数据点个数
for i in range(dataRowCount):
dateStr = self.itemModel.item(i, 0).text() #日期字符串，如"2017/02/03"
dateValue = QDate.fromString(dateStr, "yyyy/MM/dd") #QDate
dtValue = QDateTime(dateValue) #日期时间 QDateTime
timeStamp = dtValue.toMSecsSinceEpoch() #毫秒数
oneCandle = QCandlestickSet() #QCandlestickSet
oneCandle.setOpen(float(self.itemModel.item(i, 1).text())) #开盘
oneCandle.setHigh(float(self.itemModel.item(i, 2).text())) #最高
oneCandle.setLow(float(self.itemModel.item(i, 3).text())) #最低
oneCandle.setClose(float(self.itemModel.item(i, 4).text())) #收盘
oneCandle.setTimestamp(timeStamp) #时间戳
seriesCandle.append(oneCandle) #添加到序列
M1 = float(self.itemModel.item(i, 5).text())
M2 = float(self.itemModel.item(i, 6).text())
M3 = float(self.itemModel.item(i, 7).text())
M4 = float(self.itemModel.item(i, 8).text())
seriesMA1.append(timeStamp, M1)
seriesMA2.append(timeStamp, M2)
seriesMA3.append(timeStamp, M3)
seriesMA4.append(timeStamp, M4)
## 4. 设置坐标轴范围
minDateStr = self.itemModel.item(0, 0).text() #日期字符串，如"2017/02/03"
minDate = QDate.fromString(minDateStr, "yyyy/MM/dd") #QDate
minDateTime = QDateTime(minDate) #最小日期时间,QDateTime
maxDateStr = self.itemModel.item(dataRowCount - 1,
0).text() #日期字符串，如"2017/05/03"
maxDate = QDate.fromString(maxDateStr, "yyyy/MM/dd")
maxDateTime = QDateTime(maxDate) #最大日期时间
self.__axisX.setRange(minDateTime, maxDateTime) #日期时间范围
dateFormat = self.ui.comboDateFormat.currentText() #格式，如"MM-dd"
self.__axisX.setFormat(dateFormat) #标签格式
self.__axisY.applyNiceNumbers() #自动
for marker in self.chart.legend().markers(): #QLegendMarker类型列表
marker.clicked.connect(self.do_LegendMarkerClicked)
