销售分析部分包含按月分析的簇状图和按类别分析的饼图，如下：
1 页面设计
设计该页面其实很简单，说白了就是两个也切tab类以及饼图和簇状图。打开QTDesiger，按下图添加控件，并重命名如下：
2 按类别分析
#按类别功能函数
def analyByType(self):
#创建QPieSeries对象，用来存放饼图的数据
pseries=QPieSeries()
for item in typeset.items():
pseries.append(item[0], item[1])
slice=pseries.slices()[0]
slice.setExploded(True)
slice.setLabelVisible(True)
slice.setPen(QPen(Qt.GlobalColor.red,2))
slice.setBrush(Qt.GlobalColor.red)
#创建QChart实例
chart=QChart()
chart.addSeries(pseries)
chart.createDefaultAxes()
#设置图表
chart.setTitle("商品按类别销售数据分析")
#动画效果
chart.setAnimationOptions(QChart.AnimationOption.SeriesAnimations)
chart.legend().setVisible(True)
chart.legend().setAlignment(Qt.AlignmentFlag.AlignBottom)
#2显示图表
chartView=QChartView(chart)
#绘制平滑
chartView.setRenderHint(QPainter.RenderHint.Antialiasing)
self.layout1=QGridLayout(self.frmType)
self.layout1.addWidget(chartView)
3 按月分析
#按月份
def analyByMonth(self):
bseries=QBarSeries()
lseries=QLineSeries()
#添加数据
monthset=QBarSet('')
for i in range(0,12):
monthset << money_m[i]
lseries.append(i, money_m[i])
bseries.append(monthset)
lseries.setColor(QColor(255,0,0))
#创建QChart实例
chart=QChart()
#不显示图例
chart.legend().hide()
chart.addSeries(bseries)
chart.addSeries(lseries)
#设置坐标
axis_x=QBarCategoryAxis()
axis_x.setTitleText('月份')
axis_x.append(month)
chart.addAxis(axis_x,Qt.AlignmentFlag.AlignBottom)
lseries.attachAxis(axis_x)
axis_y=QValueAxis()
axis_y.setTitleText('金额（元）')
axis_y.setLabelFormat("%d")
chart.addAxis(axis_y,Qt.AlignmentFlag.AlignLeft)
lseries.attachAxis(axis_y)
#设置图表
chart.setTitle("商品按月份销售数据分析")
chart.setAnimationOptions(QChart.AnimationOption.SeriesAnimations)
chart.setTheme(QChart.ChartTheme.ChartThemeLight)
#用chartView显示图表
chartView=QChartView(chart)
chartView.setRenderHint(QPainter.RenderHint.Antialiasing)
self.layout2=QGridLayout(self.frmMonth)
self.layout2.addWidget(chartView)
