plt.show() 在上面的示例中,我们首先使用subplots函数创建了一个坐标轴对象ax。然后,使用ax对象的plot函数绘制了数据点。接下来,使用ax对象的text函数在坐标轴上添加了相对坐标文本。ha和va参数用于设置文本的水平对齐方式和垂直对齐方式,这里设置为居中对齐(ha=’center’和va=’center’)。运行代码后,将显示一个包...
修正后的代码: python import matplotlib.pyplot as plt # 创建图形对象 fig, ax = plt.subplots() ax.plot([1, 2, 3], [1, 4, 9]) plt.show() 综上所述,解决“name 'fig' is not defined”错误的关键在于确保在使用变量之前已经正确定义了它,并且检查代码中是否有误用或误写的情况。
