Question

我需要比较光谱列表的多个版本，我正在为每个光谱生成一个图形对象，我计划在其中显示相同光谱的不同版本。每个频谱的每个版本都有两个＆＃34;翅膀＆＃34;我想在同一页面上显示。为此我做了一些事情（我将光谱表示为numpy数组，我通常从fit文件中获取它们）：

import os
import sys
import numpy as np
import matplotlib.pyplot as mplt
import matplotlib.gridspec as gs
import numpy.random as rnd

PageGrid = gs.GridSpec( 11, 1, hspace = 0.0)

Spec1 = rnd.randint(1, 100, 100)
Spec2 = rnd.randint(1, 100, 100)
Spec3 = rnd.randint(1, 100, 100)

LeftSpecList = ['Spec1', 'Spec2', 'Spec3']

RightSpecList = ['Spec1', 'Spec2', 'Spec3']

for leftSpec in LeftSpecList:
    fig = mplt.figure(str(leftSpec))
    axTop = fig.add_subplot( PageGrid[:5, :] )
    axTop.plot(eval(leftSpec))


for rightSpec in RightSpecList:
    fig = mplt.figure(str(rightSpec))
    axBottom = fig.add_subplot( PageGrid[6:, :] )       
    axBottom.plot(eval(rightSpec))

然后我有第二个光谱列表，我想在其他光谱上绘制（可能有或没有相同的长度）：

LeftSpecListNew = ['Spec1', 'Spec2']

RightSpecListNew = ['Spec2', 'Spec3']

for leftSpec in LeftSpecList:
    fig = mplt.figure(str(leftSpec))
    axTop.plot(eval(leftSpec))


for rightSpec in RightSpecList:
    fig = mplt.figure(str(rightSpec))
    axBottom.plot(eval(leftSpec))

mplt.show()

但是当我这样做时，它会在第一个数字上打印出来。有什么想法吗？

axTop和axBottom在前两个循环中被覆盖。您需要跟踪每个图形的每个顶部和底部轴。这样的事情应该做你想要的。

axTopDict = {}
for leftSpec in LeftSpecList:
    fig = mplt.figure(str(leftSpec))
    axTop = fig.add_subplot( PageGrid[:5, :] )
    axTop.plot(eval(leftSpec),'ro')
    axTopDict[leftSpec] = axTop # associate this axis with this figure name 

axBottomDict = {}
for rightSpec in RightSpecList:
    fig = mplt.figure(str(rightSpec))
    axBottom = fig.add_subplot( PageGrid[6:, :] )       
    axBottom.plot(eval(rightSpec),'b*')
    axBottomDict[rightSpec] = axBottom # associate this axis with this figure name 

LeftSpecListNew = ['Spec1', 'Spec2']

RightSpecListNew = ['Spec2', 'Spec3']

for leftSpec in LeftSpecList:
    fig = mplt.figure(str(leftSpec))
    axTop = axTopDict[leftSpec] # get the top axis associated with this figure name
    axTop.plot(eval(leftSpec),'m')


for rightSpec in RightSpecList:
    fig = mplt.figure(str(rightSpec))
    axBottom = axBottomDict[rightSpec] # get the bottom axis associated with this figure name
    axBottom.plot(eval(leftSpec),'g')

mplt.show()

返回matplotlib中先前生成的轴
