如何用 Python 绘制带有区间边界的散点图？

a：core1, up1, down1, core2, up2, down2b：core1, up1, down1, core2, up2, down2c：core1, up1, down1, core2, up2, down2

import matplotlib.pyplot as pltimport numpy as np

fig, ax = plt.subplots(1, 2)  # 1 行 2 列的画布

data = {    "a": [1, 2, 3, 4, 5, 6],    "b": [2, 3, 4, 5, 6, 7],    "c": [3, 4, 5, 6, 7, 8]}cores = ["core1", "core2"]

for key in data.keys():    for i, core in enumerate(cores):        y = data[key]        up = data[key][i*3+1::2]        down = data[key][i*3+2::2]        ax[i].errorbar(key, y, yerr=[down, up], fmt='o', capsize=5, linewidth=1.5)

for i, axi in enumerate(ax):    axi.set_ylabel("value")    axi.set_title(f"core {i+1}")

plt.show()
