Matplotlib pyplot散射轴是无序的

Question

为什么我的散点图在Y轴上看起来像这样？我希望它以有序的方式进行！

这是代码：

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
x = pd.DataFrame.from_dict({"Main":{183: 12.0, 145: 9.8, 130: 8.2, 182: 11.9, 146: 9.9, 99: 22.9, 3: 22.0, 9: 22.5, 186: 12.2, 77: 21.7, 69: 21.0, 87: 22.7, 139: 9.2, 5: 22.0, 152: 10.4, 61: 22.5, 229: 26.1, 14: 23.1, 230: 26.2, 201: 12.7, 103: 23.1, 101: 23.0, 199: 12.8, 188: 12.3, 37: 21.3, 2: 22.0, 179: 11.5, 66: 20.9, 144: 9.7, 16: 23.2, 196: 12.6, 15: 23.1, 216: 24.8, 110: 23.2, 133: 8.5, 165: 12.3, 107: 23.2, 109: 23.2, 224: 26.5, 6: 22.1, 90: 22.7, 91: 22.7, 223: 26.4, 13: 23.0, 35: 21.2, 173: 10.6, 58: 22.4, 160: 11.0, 39: 21.5, 232: 26.2, 120: 22.2, 202: 12.7, 169: 9.9, 170: 10.1, 8: 22.4, 137: 8.9, 197: 12.6, 65: 20.9, 73: 21.3, 93: 22.9, 114: 23.3, 180: 11.7, 159: 11.0, 127: 8.1, 60: 22.5, 42: 21.6, 72: 21.2, 105: 23.2, 55: 22.1, 221: 26.3, 121: 22.2, 207: 23.4, 29: 20.9, 151: 10.4, 166: 12.3, 122: 22.5, 27: 20.9, 218: 26.1, 79: 21.9, 32: 21.0, 154: 10.6, 210: 24.3, 205: 22.8, 131: 8.3, 56: 22.2, 185: 12.1, 123: 22.6, 135: 8.7, 234: 24.8, 36: 21.3, 108: 23.2, 83: 22.3, 172: 10.4, 147: 10.0, 136: 8.8, 7: 22.2, 49: 21.9, 85: 22.5, 18: 23.3, 231: 26.5, 134: 8.6, 43: 21.7, 82: 22.2, 89: 22.7, 235: 23.3, 141: 9.4, 22: 21.0, 17: 23.3, 195: 12.6, 174: 10.8, 162: 11.6, 95: 22.7, 97: 22.7, 23: 21.0, 140: 9.3, 142: 9.5, 98: 22.8, 132: 8.4, 129: 8.2, 104: 23.2, 96: 22.7, 158: 10.9, 40: 21.5, 215: 25.2, 4: 22.0, 0: 22.0, 12: 22.9, 217: 25.9, 222: 26.4, 80: 22.0, 70: 21.1, 233: 26.2, 138: 9.0, 193: 12.5, 92: 22.8, 192: 12.5, 124: 22.5, 59: 22.4, 150: 10.3, 176: 11.1, 225: 26.5, 38: 21.4, 167: 9.9, 44: 21.7, 113: 23.3, 112: 23.3, 214: 25.2, 155: 10.7, 52: 21.9, 220: 26.3, 63: 22.6, 74: 21.3, 184: 12.0, 187: 12.3, 41: 21.6, 26: 20.9, 33: 21.1, 11: 22.8, 117: 23.1, 190: 12.4, 177: 11.3, 34: 21.1, 219: 26.2, 53: 22.0, 161: 11.1}})

ax.scatter(x.Main, y, s=100, marker="x")

EDIT2：缺少数据......

Answer 1

鉴于数据，该问题现在可以重现。

您正在尝试绘制完整的DataFrame y。这使matplotlib感到困惑。 而是选择要绘制的列，

ax.scatter(x.Main, y.Real, s=100, marker="x")

结果如下：
