python3 configure.py --qmake /home/oo/Qt/5.14.0/gcc_64/bin/qmake
make
sudo make install

成功的

我试图将绘图烛台和 5 天平均线放在同一个 qtchart 上，但将两个 x 轴绘图代码放入 UI 加载程序

uifile_1 = 'UI/main.ui'
form_1, base_1 = uic.loadUiType(uifile_1)

uifile_2 = 'UI/main1.ui'
form_2, base_2 = uic.loadUiType(uifile_2)

我有一个 PyQt 图表，但 X 轴水平显示数据。

如何垂直显示 X 轴上的标签？

我想要的结果是这样的（原谅糟糕的Photoshop技能！！）

我想让饼图的每一片都成为我选择的颜色。我需要知道 QPieSlice 的 snytax（如果这是我使用的）以及如何将颜色附加到馅饼的特定切片上。例如，我希望“自动”切片为“#00FF00”，“就业”切片为“#1A8CFF”等。

下面是我的馅饼的碎片。我尝试过各种事情，例如：

QPieSlice.setBrush(QPieSlice.setColor(QColor('#00FF00')))

但它不起作用，即使它起作用了，我也不知道如何将它附加到特定的切片以及将它放在哪里。

series.append("Auto", self.expensesWindow.piechart[0])
series.append("Employment", self.expensesWindow.piechart[1])
series.append("Insurance", self.expensesWindow.piechart[2])
series.append("Household", self.expensesWindow.piechart[3])
series.append("Housing", self.expensesWindow.piechart[4])
series.append("Entertainment", self.expensesWindow.piechart[5])
series.append("Utilities", self.expensesWindow.piechart[6])
series.append("Other", self.expensesWindow.piechart[7])
