如何访问熊猫数据透视表数据

Question

I have this pivot table:

d = c.pivot_table(index=[ 'Material'], columns = ['MvT'], values=['Quantity'], aggfunc=[np.sum],fill_value=0, margins = True)

sum
Quantity
  MvT       601  631  641   All
  Material              
 Type_A      9    2    5    16
 Type_B      6    4    10   20
 Type_C      3    0    2     5
 Type_D      3    2    1     6
 Type_E      1    0    1     2

  All       22    8   19    49

I want to display by matplotlib BAR 'All'. How can I access to 'All'?

d.loc[:,'All']

doesn't work

KeyError: 'All'

Change [np.sum] to np.sum , you create a multiple index

d = c.pivot_table(index='Material', columns = 'MvT', values='Quantity', aggfunc=np.sum,fill_value=0, margins = True)

then

d.loc[:,'All']
