我有这个代码：

ax = fig.add_axes([0.1, 0.1, 0.55, 0.8])

我想在args.avg_windowax 的 x 轴上设置一个下限。我尝试使用 xlim、set_xlim、set_xbound，现在添加xrange=(args.avg_window, args.posts_limit)到该函数调用，但似乎没有任何效果：

和

ax = fig.add_axes([0.1, 0.1, 0.55, 0.8], xrange=(args.avg_window, args.posts_limit))

我收到此错误：

和

ax.set_xlim(left = args.avg_window)

我收到此错误：

我做错了什么，我能做些什么来设置轴的界限？

在您的第一次调用中，这是一个错误的关键字参数：要设置 x 轴限制，您应该传递xlim给add_axes：

ax = fig.add_axes([0.1, 0.1, 0.55, 0.8], xlim=(args.avg_window, args.posts_limit))

之后设置轴限制

ax.set_xlim(left=args.avg_window)

为我工作。也许您之前的代码出了问题，或者您的 matplotlib 版本中确实没有实现。我使用 1.2 版。

您args.avg_window被存储为用户输入返回的字符串。在将其作为 matplotib 轴限制参数传递之前，您需要将其转换int()为 a，无论您想采用哪种方式。

set_xlim(int(args.avg_window), right=1)

将设置最小 x 轴限制，同时保持最大值不变。
