Graphql-engine: Add advanced example for aggregation queries

[marionschleifer]

The examples we have here: https://docs.hasura.io/1.0/graphql/manual/queries/aggregation-queries.html#aggregation-queries are quite basic.

We can add a more advanced example here.

Hello, can I work on this issue?

[marionschleifer]

@wdtamagi sure you can work on it. We created a wiki that describes how to contribute: https://github.com/hasura/graphql-engine/wiki/Hacktoberfest-2019-%F0%9F%8E%89 🙂

Thanks @marionschleifer

[wdtamagi]

I need create new advanced example or change current examples?

Creating a new item in the table of contents, such as "Fetch Aggregate Data - Advanced Example"?

[wdtamagi]

Or just need update documentation based on https://docs.hasura.io/1.0/graphql/manual/api-reference/graphql-api/query.html#aggregateobject
?

@marionschleifer Let's talk to other folks on the team to discuss what kinds of examples we should add for aggregations? I think @rikinsk and @0x777 had a list...

[wdtamagi]

Great, I included the other aggregation functions: stddev, stddev_samp, stddev_pop, variance, var_samp, var_pop on documentation page.

Current documentation only displays functions: count, sum, avg, max and min.

Hi everyone, we couldn't come up with an example to improve this. So I'm closing this now. Sorry to those who wanted to work on this 🙏
