iPython Notebook中的传奇不透明度

Question

我在Python 3中使用最新版本的iPython Notebook来显示使用%matplotlib inline的图表。情节中的传说没有背景，底层数字显示出来。当我使用终端或IDE创建绘图时，图例是不透明的。如何使iPython Notebook中的图例也不透明？

py.rcParams['xtick.major.pad'] = 8
py.rcParams['ytick.major.pad'] = 8
py.rcParams['lines.linewidth'] = 2
py.rcParams['legend.fontsize'] = 12
py.rcParams['legend.fancybox'] = True
py.rcParams['axes.grid'] = True

py.figure(2, figsize=(14,6))

py.subplot(1,2,1)
py.plot(t, co, label='co')
py.plot(t, co2, label='co2')
py.plot(t, ch2o, label='ch2o')
py.plot(t, hcooh, label='hcooh')
py.plot(t, ch4, label='ch4')
py.plot(t, glyox, label='glyox')
py.plot(t, c2h4o, label='c2h4o')
py.title('Cellulose Species, T = {} K'.format(Tinf))
py.xlabel('Time (s)')
py.ylabel('Mass Fraction')
py.legend(loc='best', numpoints=1)

py.subplot(1,2,2)
py.plot(t, haa, label='haa')
py.plot(t, c3h6o, label='c3h6o')
py.plot(t, hmfu, label='HMFU')
py.plot(t, lvg, label='LVG')
py.plot(t, h2, label='h2')
py.plot(t, h2o, label='h2o')
py.plot(t, char, label='char')
py.title('Cellulose Species, T = {} K'.format(Tinf))
py.xlabel('Time (s)')
py.legend(loc='best', numpoints=1)

py.show()

Answer 1

试试这个：

创建图例时，请将其指定给变量，例如legend，然后添加以下行：

legend.get_frame().set_fc('w')
legend.get_frame().set_alpha(1)
legend.set_zorder(99)

这将使图例的背景变为白色并位于线条前面。
