```auto
query MyQuery {
  EVM(dataset: archive, network: eth) {
    MinerRewards(limit: {count: 10}, orderBy: {ascending: Block_Number}) {
      Reward {
        Total
        ..... 
      }
      Block {
        Number
        Time
      }
    }
  }
}

```

give me duplicate entries with the same height

```auto
{
        "Block": {
          "Number": "4",
          "Time": "2015-07-30T15:27:57Z"
        },
        "Reward": {
          "BurntFees": "0.000000000000000000",
          "Dynamic": "0.000000000000000000",
          "Static": "0.000000000000000000",
          "Total": "3.125000000000000000",
          "TxFees": "0.000000000000000000"
        }
      },
      {
        "Block": {
          "Number": "4",
          "Time": "2015-07-30T15:27:57Z"
        },
        "Reward": {
          "BurntFees": "0.000000000000000000",
          "Dynamic": "0.000000000000000000",
          "Static": "5.000000000000000000",
          "Total": "5.156250000000000000",
          "TxFees": "0.000000000000000000"
        }
      },

```

Please try this query, it will solve your problem

```grpahl
query MyQuery {
  EVM(dataset: archive, network: eth) {
    MinerRewards(
      limitBy: {by: Block_Number, count: 1}
      limit: {count: 10}
      orderBy: {ascending: Block_Number}
    ) {
      Reward {
        Total
      }
      Block {
        Number
        Time
      }
    }
  }
}
```
