속성 설정 및 가져오기 #

pyplot 인터페이스를 사용하면 개체 속성을 각각 사용 setp하고 getp설정하고 가져올 수 있을 뿐만 아니라 개체에 대한 검사를 수행할 수 있습니다.

# 으로 설정setp

점선으로 표시할 선의 선 스타일을 설정하려면 다음을 사용합니다 setp.

>>> line, = plt.plot([1, 2, 3])
>>> plt.setp(line, linestyle='--')

유효한 인수 유형을 알고 싶다면 값 없이 설정하려는 속성의 이름을 제공할 수 있습니다.

>>> plt.setp(line, 'linestyle')
    linestyle: {'-', '--', '-.', ':', '', (offset, on-off-seq), ...}

설정할 수 있는 모든 속성과 가능한 값을 보려면 다음을 수행할 수 있습니다.

>>> plt.setp(line)

setp단일 인스턴스 또는 인스턴스 목록에서 작동합니다. 가능한 값을 검사하는 쿼리 모드에 있는 경우 시퀀스의 첫 번째 인스턴스만 사용됩니다. 실제로 값을 설정하면 모든 인스턴스가 설정됩니다. 예를 들어 두 줄의 목록이 있다고 가정하면 다음은 두 줄을 모두 두껍고 빨간색으로 만듭니다.

>>> x = np.arange(0, 1, 0.01)
>>> y1 = np.sin(2*np.pi*x)
>>> y2 = np.sin(4*np.pi*x)
>>> lines = plt.plot(x, y1, x, y2)
>>> plt.setp(lines, linewidth=2, color='r')

# 으로 받기getp

getp주어진 속성의 값을 반환합니다. 이를 사용하여 단일 속성 값을 쿼리할 수 있습니다.

>>> plt.getp(line, 'linewidth')
    0.5

또는 모든 속성/값 쌍:

>>> plt.getp(line)
    aa = True
    alpha = 1.0
    antialiased = True
    c = b
    clip_on = True
    color = b
    ... long listing skipped ...

별칭 #

대화형 모드에서 키 입력을 줄이기 위해 여러 속성에 짧은 별칭이 있습니다(예: 'linewidth'의 'lw' 및 'markeredgecolor'의 'mec'). 인트로스펙션 모드에서 set 또는 get을 호출할 때 이러한 속성은 'fullname' 또는 'aliasname'으로 나열됩니다.
