I've been trying for days to get the following result:

I have this dataset:

e1 = g.addV('company').property('name', 'company-1').next()
e2 = g.addV('company').property('name', 'company-2').next()
p1 = g.addV('product').property('name', 'product-1').next()
p2 = g.addV('product').property('name', 'product-2').next()
p3 = g.addV('product').property('name', 'product-3').next()
i1 = g.addV('tax').property('name', 'tax-1').next()
i2 = g.addV('tax').property('name', 'tax-2').next()
g.addE('taxes').from(i1).to(p1).property('amount', 10)
g.addE('taxes').from(i2).to(p2).property('amount', 15)
g.addE('taxes').from(i1).to(p3).property('amount', 20)
g.addE('taxes').from(i2).to(p3).property('amount', 20)
g.addE('sells').from(e1).to(p1).property('price', 10)
g.addE('sells').from(e1).to(p2).property('price', 15)
g.addE('sells').from(e2).to(p2).property('price', 20)
g.addE('sells').from(e2).to(p3).property('price', 25)

And I need to sum all the products that a company sells( company-1 = 25, company-2 = 45 ). Currently I'm stuck at the following query:

g.V().hasLabel('company').as('e').outE('sells').as('f').inV().as('p').inE('taxes').as('i').outV().select('e', 'p', 'f', 'i').by('name').by('name').by('price').by('amount').group().by('e')

Any tips on how I may accomplish this? Also, if someone could give me an example of how I could do the sum, but taking in account the taxes, like: value = product * (1 + (amount/100))

我认为这可以通过首先按公司分组然后对边缘的价格求和来满足您的需求：

g.V().hasLabel('company').as('e').
    outE('sells').as('f').
    group().
        by(select('e').values('name')).
        by(values('price').sum())
