Python plt.text中重叠，包adjust_text不起作用，如何修复

这是对重叠较少的try ，但如果事情发生很大变化，则需要进行一些调整.ax.annotate完成了大部分工作，但有一些填充参数可用于额外调整.主要 idea 是将蓝色标签向左移动，将橙色标签向右移动.

其中一个橙色标签与线重叠.如果需要一次性情节，您可以手动强制关闭它，但我没有这样做，以便使答案更通用且对新 case 更稳健.

from matplotlib import pyplot as plt

pr_x = [-1, -0.5, 0, 0.5, 1]
pr_y = [1, 0.683, 0.067, 0.5, 1]
color_pr = 'tab:blue'

pr1000_x = [-1, -0.5, 0, 0.5, 1]
pr1000_y = [1, 0.983, 0.05, 0.917, 1]
color_pr1000 = 'tab:orange'

f, ax = plt.subplots(figsize=(6, 3))
ax.plot(pr_x, pr_y, color=color_pr, marker='o', label='n=500')
ax.plot(pr1000_x, pr1000_y, color=color_pr1000, marker='o', label='n=1000')

ax.set(xlabel='x', ylabel='y', title='curve high vs low, gtype2')
ax.legend()

for x, y in zip(pr_x, pr_y):
    ax.annotate(
        f'{y:.3f}', (x, y),
        xytext=(-0.6, 0), textcoords='offset fontsize', #shift blue pts left
        horizontalalignment='right', verticalalignment='center',
        weight='bold', fontsize=8, color=color_pr,
    )
    
for x, y in zip(pr1000_x, pr1000_y):
    ax.annotate(
        f'{y:.3f}', (x, y),
        xytext=(0.6, 0.2), textcoords='offset fontsize', #shift orange pts up, right
        horizontalalignment='left', verticalalignment='bottom',
        weight='bold', fontsize=8, color=color_pr1000,
        # rotation=20
    )
    
ax.set_xlim(ax.get_xlim()[0] * 1.15, ax.get_xlim()[1]) #make x axis wider
ax.spines[['right', 'top']].set_visible(False)

这是重叠可能性较小的替代安排.每个情节都有一个视觉指南，但数字分为两个情节.

我认为，如果您有兴趣进一步探索这种安排，seaborn的FacetGrid可以用更少的代码来完成类似的事情.

f, axs = plt.subplots(ncols=2, nrows=1, figsize=(7, 3), sharey=True, layout='tight')

pr_data = (pr_x, pr_y, 'n=500')
pr1000_data = (pr1000_x, pr1000_y, 'n=1000')

for ax in axs:
    fg_data = pr_data if ax==axs[0] else pr1000_data
    bg_data  = pr_data if ax==axs[1] else pr1000_data
    
    #Foreground data
    x, y, label = fg_data
    ax.plot(x, y, 'tab:purple', marker='o', markersize=7, linewidth=3, label=label)
    
    for x_i, y_i in zip(x, y):
        ax.annotate(
            f'{y_i:.3f}', (x_i, y_i), xytext=(1, 0.6), textcoords='offset fontsize',
            horizontalalignment='left', verticalalignment='top',
            color='midnightblue', weight='bold', size=8, rotation=0,
        )
    
    #Background data
    x, y, label = bg_data
    ax.plot(x, y, 'black', marker='o', markersize=6,
            linewidth=4.5, linestyle='-', alpha=0.12,
            label=label, zorder=0)
    
    ax.set_xlabel('x')
    ax.spines[['right', 'top']].set_visible(False)
    ax.set_title(label, color='rebeccapurple', weight='bold')
    # ax.legend()

    axs[0].set_ylabel('y')
