pyqt5 根据坐标点绘图，坐标图中会有10个点相连接，且其中某两个点连接线段是一段圆弧，图像绘制好后将其置于窗口中心，且图像大小适应窗口大小

以下是一个简单的示例代码，实现了根据给定坐标点绘制图形，并将其置于窗口中心并适应窗口大小。

import sys
from PyQt5.QtWidgets import QWidget, QApplication
from PyQt5.QtGui import QPainter, QPen, QBrush
from PyQt5.QtCore import Qt, QPoint, QRectF


class MyWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.setGeometry(100, 100, 800, 600)
        self.setWindowTitle('My Widget')
        self.points = [
            QPoint(100, 100),
            QPoint(200, 150),
            QPoint(300, 150),
            QPoint(400, 100),
            QPoint(500, 200),
            QPoint(400, 300),
            QPoint(300, 250),
            QPoint(200, 300),
            QPoint(100, 250),
            QPoint(200, 200)
        ]

    def paintEvent(self, event):
        painter = QPainter(self)
        painter.setRenderHint(QPainter.Antialiasing)
        painter.translate(self.width() / 2, self.height() / 2)
        painter.scale(min(self.width(), self.height()) / 600, min(self.width(), self.height()) / 600)
        pen = QPen(Qt.black, 2)
        brush = QBrush(Qt.SolidPattern)

        # 绘制连接线
        painter.setPen(pen)
        for i in range(len(self.points) - 1):
            painter.drawLine(self.points[i], self.points[i + 1])

        # 绘制圆弧
        painter.setBrush(brush)
        painter.drawArc(QRectF(self.points[3], self.points[4] - self.points[3]), 0, 180 * 16)

        # 绘制点
        for point in self.points:
            painter.drawEllipse(point, 5, 5)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = MyWidget()
    widget.show()
    sys.exit(app.exec_())

运行结果如下：
