Introduction

There are 2 ways to apply a widget filter :

  • on the raw values : each row in the raw dataset is evaluated against the filter condition
  • on the aggregated values : the raw dataset is first aggregated by the Widget, and only then the filter condition is applied

Example

The Data Source

Imagine a simple dataset :

TagName Building Product Price
FT101.Value Building A Product X 10
FT102.Value Building A Product Y 15
FT201.Value Building B Product X 20
FT202.Value Building B Product Y 25
FT301.Value Building C Product X 30
FT302.Value Building C Product Y 35

The Widget

You are displaying this data in a Pie Chart with Sum(Price) grouped by “Product”, you get :

Product Sum(Price)
Product X 60
Product Y 75

Filtering raw values

You apply a filter on the raw value to see only data where :
Price > 20

The raw dataset will be filtered like this :

TagName Building Product Price
FT202.Value Building B Product Y 25
FT301.Value Building C Product X 30
FT302.Value Building C Product Y 35

And the Widget will display the following :

Product Sum(Price)
Product X 30
Product Y 60

(because 60 = 25 + 35)

Filtering aggregated values

You apply a filter on the aggregated value to see only data where :
Sum(Price) > 70

It is not the raw dataset that will be filtered.
The Widget will display the following :

Product Sum(Price)
Product Y 75

(Product X was filtered because its Sum(Price) was 60 <= 70)

How to filter by aggregated values

For each filter condition, you can check Use Field Aggregate :

Widget filter aggregated

Then select the desired aggregation function :

Widget filter aggregated functions

Note on non-numerical fields

On fields where the data type is not number (string, date, boolean), the aggregation functions will return a number, so the condition becomes a number condition.
For those fields, the list of available aggregation functions is also different :

Widget filter aggregated functions string

For example, the resulting filter condition below reads as :
Distinct Count of EquipmentName < 3

Widget filter aggregated string condition
