Hi Jose,

Are you referring to the values that appear on top of the Reading column header?

If so, those can be configured by using the Options attribute | DataMiner Docs

With it, you can select between

• Sum (enableHeaderSum)
  which is the default value and if you want nothing to be shown you can use disableHeaderSum
• Average (enableHeaderAvg)
• Max (enableHeaderMax)
• Min (enableHeaderMin)

If you need different calculations or something else then your best option is to go with Koen's suggestion.
