我的绘图脚本为每个标签创建了两个图例。我不知道如何使 legend() 不重复。我检查了stackoverflow，发现了两种方法。但我无法在这里实现它们。有任何想法吗？
symbols = [u'\u2193']
#Plotting our vsini values
for i, symbol in enumerate(symbols):
for x0,y0 in zip(vsini_slit_cl, vsini_slit):
plt.text(x0,y0, symbol, fontname='STIXGeneral', size = 10, va='center', ha='center', clip_on=True,color = '#737373')
for i, symbol in enumerate(symbols):
for x0, y0 in zip(vsini_cl_sl, vsini_sl):
plt.text(x0, y0, symbol, fontname='STIXGeneral', size = 10, va='center', ha='center', clip_on=True)
# PLOTTING VSINI FROM LITERATURE
plt.plot((vmag_lit-jmag_lit), vsini_lit, 'o', color = '#a6a6a6', label='Literature')
# PLOTTING SLOW VSINI FROM LITERATURE
plt.plot(vsini_slit_cl, vsini_slit, 'o', color = '#a6a6a6')
# PLOTTING VSINI FROM OUR WORK
plt.plot(vsini_cl_sl, vsini_sl, 'o', label='This Work' )
plt.errorbar(vsini_color, vsini_chad, yerr=vsini_chad_sig, fmt='bo', capsize=3)
plt.legend()
plt.savefig('vsini_colors.jpg', dpi=200)
