用 Python 写一个更大的 Circumflex

Question

我可以在 Python 中将 'A circumflex' 写为图表上的标签：

df = pd.DataFrame({'x':(0,3,4,0),'y':(3,0,4,3)})

fig, ax = plt.subplots(1,1)

df.plot(x='x', y='y', ax=ax, label='A\u0302', linewidth=5, color='k', linestyle='-')

for item in ([ax.title, ax.xaxis.label, ax.yaxis.label] +
             ax.get_xticklabels() + ax.get_yticklabels()):
    item.set_fontsize(22)

legend = ax.legend(loc=0, ncol=1, bbox_to_anchor=(0.9, -.3, .6, 1),
           fancybox=True, shadow=False,
           framealpha=1, fontsize=22)

plt.setp(legend.get_title(),fontsize=22)

这给出了：

请问怎样才能让音圈变大？

Answer 1

感谢 T & tmdavison 先生，$^{A}$ 或 $\hat{A}$ 出于某种原因工作：

df = pd.DataFrame({'x':(0,3,4,0),'y':(3,0,4,3)})

fig, ax = plt.subplots(1,1)

df.plot(x='x', y='y', ax=ax, label='$A\u0302$', linewidth=5, color='k', linestyle='-')
df.plot(x='x', y='y', ax=ax, label='$\^{A}$',   linewidth=5, color='k', linestyle='-')
df.plot(x='x', y='y', ax=ax, label='$\hat{A}$', linewidth=5, color='k', linestyle='-')

for item in ([ax.title, ax.xaxis.label, ax.yaxis.label] +
             ax.get_xticklabels() + ax.get_yticklabels()):
    item.set_fontsize(22)

legend = ax.legend(loc=0, ncol=1, bbox_to_anchor=(0.9, -.3, .6, 1),
           fancybox=True, shadow=False,
           framealpha=1, fontsize=22)

plt.setp(legend.get_title(),fontsize=22)
