Matplotlib / df.plot()：为浮点数谱设置自定义整数 xticks
Matplotlib / df.plot(): set custom integer xticks for spectrum of floats
编辑：请注意我在 x 轴（和浮点数）中有更多我想要刻度（整数）的值，这使得通常的解决方案不起作用（如 Why set_xticks doesn't set the labels of ticks?）
我在 x 轴上有一个 3197 个浮点数的数组，在 y 轴上有相应的值：

我想绘制 xticks 为：
[0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100]
但我找不到好的解决方案。
matplotlib / df.plot() 给我的默认值是：
和ax.set_xticks(range(0, 100, 2))以及类似的给我：
你可以试试：
# set the x tick positions
ax.set_xticks(list(range(0, 101, 2)))
# now set the xtick labels at those positions
ax.set_xticklabels([f"{int(xval)}" for xval in range(0, 101, 2)])
请注意 range 转到 101，因此它包含数字 100。
谢谢大家花时间回答，但我显然不是很聪明。
我忘了检查类型，而不是浮点数，我有字符串
df = df.astype('float64')
df.index = df.index.astype('float64')
编辑：请注意我在 x 轴（和浮点数）中有更多我想要刻度（整数）的值，这使得通常的解决方案不起作用（如 Why set_xticks doesn't set the labels of ticks?）
我在 x 轴上有一个 3197 个浮点数的数组，在 y 轴上有相应的值：
0.16 0.19 0.22 0.25 0.28 0.31 0.34 0.38 0.41 0.44 0.47 0.50 0.53 0.56 0.59 0.63 0.66 0.69 0.72 0.75 0.78 0.81 0.84 0.88 0.91 0.94 0.97 1.00 1.03 1.06 1.09 1.13 1.16 1.19 1.22 1.25 1.28 1.31 1.34 1.38

99.84 99.88 99.91 99.94 99.97 100.00
我想绘制 xticks 为：
[0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100]
但我找不到好的解决方案。
matplotlib / df.plot() 给我的默认值是：
和ax.set_xticks(range(0, 100, 2))以及类似的给我：
你可以试试：
# set the x tick positions
ax.set_xticks(list(range(0, 101, 2)))
# now set the xtick labels at those positions
ax.set_xticklabels([f"{int(xval)}" for xval in range(0, 101, 2)])
请注意 range 转到 101，因此它包含数字 100。
谢谢大家花时间回答，但我显然不是很聪明。 我忘了检查类型，而不是浮点数，我有字符串
df = df.astype('float64')
df.index = df.index.astype('float64')
