## Timeseries

`kangaData.timeseries({blocks = [], timestamps = [], target = targetFunction}, {targetArguments})` Returns an array of queries. Blocks / timestamps are arrays of the blocks / timestamps to query (choose one). The target is the target function, the target arguments are the arguments for the target. See example below

## Example

```javascript
const kangaData = require('@kangafinance/kanga-data'); // common js
// or
import kangaData from '@kangafinance/kanga-data'; // es modules

// query and log resolved results
kangaData.masterbreeder
  .pools({block: 11223344})
  .then(pools => console.log(pools))

kangaData.timelock
  .allTxs({minTimestamp: 1605239738, maxTimestamp: 1608239738})
  .then(txs => console.log(txs))

kangaData.billabong
  .user({user_address: '0x6684977bbed67e101bb80fc07fccfba655c0a64f'})
  .then(user => console.log(user))

kangaData.exchange
  .observePairs()
  .subscribe({next: (pairs) => console.log(pairs), error: (err) => console.log(err)})

kangaData
  .timeseries({blocks: [11407623, 11507623, 11607623], target: kangaData.exchange.pair}, {pair_address: "0x795065dCc9f64b5614C407a6EFDC400DA6221FB0"})
