### Usage Demo ####
mf = multifig(figsize_y,figsize_x,fignum_y,fignum_x,figscale=1.,scheme='1fig1bar') # fixed_width=None,fixed_height=None 可选
########## 参数说明 ####################################################
# figsize_y -> 子图的纵向尺寸
# figsize_x -> 子图的横向尺寸
# *** (默认) 将子图的横向宽度设定为 单位长度。因而纵向长度为 figsize_y / figsize_x
# *** 这样一来 子图的长宽比例固定，且方便多图排版。
# *** 如果尺寸不合适， 可通过 figscale 进行放大或缩小
# *** 如果想改用纵向高度为 单位长度, 可令 fixed_height=True
# fignum_y -> 纵向排列 fignum_y 张子图
# fignum_x -> 横向排列 fignum_x 张子图
# scheme -> 三种模式可供选择 '1fig1bar', 'nfig1bar', 'nfig0bar'
########################################################################
########## 初始化设置 ##################################################
# 如果不进行初始化设置,会选用默认初始化方案。
# 如果需要自定以初始化设置，各参数设定完成后, 只有通过 mf.figinit() 才能领新初始化方案生效。
mf.xmarginscale = r1 # r1>0 , r1 的值最好不要大于 1. 否则图可能不美观
mf.ymarginscale = r2 # r2>0 , r2 的值最好不要大于 1. 否则图可能不美观
mf.xspacescale = r3 # r3>0 , r3 的值最好不要大于 1. 否则图可能不美观
mf.yspacescale = r4 # r4>0 , r4 的值最好不要大于 1. 否则图可能不美观
mf.cbarspacescale = r5 # r5>0 , r5 的值最好不要大于 1. 否则图可能不美观
mf.cbarscale = r6 # r6>0 , r6 的值最好不要大于 1. 否则图可能不美观
mf.cbar_orientation = # 'y', 'x'
mf.scheme = # 1fig1bar # nfig1bar # nfig0bar
mf.figinit()
########## 初始化设置结束 ##############################################
# P.S. mf.fig --> fig
