dc.js pie-chart combine 2 columns

[spec...@gmail.com]

I have a table.

year,continent,state,export_value,import_value,all 

2013,Африка,Angola,94061754,220518.54,94282272.54 

2013,Африка,Burundi,4136818,1239175.91,5375993.91 

2013,Африка,Benin,3251643.49,65421.6,3317065.09

I need to make a pie chart enter image description here using dc.js

Problem at this point code.

    impexDim            = ndx.dimension(function (d) {return ((d.export_value > 0 ? 'Export' : 'Import') 
                                        && (d.import_value > 0 ? 'Import' : 'Export')) ;}),

    groupeimpexDim      = impexDim.group().reduceSum(function(d) {return +d.all}),

How to combine columns export_value and import_value?
