plt.errorbar(afstand, m2, xerr= None, yerr= Onn, fmt='x', mec= 'green',

plt.plot(afstand, tijd, '--', label = 'Theorie')
plt.xlabel('Afstand in $m$')
plt.ylabel('Tijd in $s$')
plt.legend()
解决方案
(没有语言环境的手动方式)
对于两个轴,我们获取当前刻度标签,然后使用列表推导对其进行替换操作;然后我们把它放回去:
ax = plt.gca() # get the current axis
# x-axis
new_x_tick_labels = [label.get_text().replace(".", ",")
for label in ax.xaxis.get_ticklabels()]
# y-axis
new_y_tick_labels = [label.get_text().replace(".", ",")
for label in ax.yaxis.get_ticklabels()]
# now set back
ax.set_xticklabels(new_x_tick_labels)
ax.set_yticklabels(new_y_tick_labels)
