Managing Calculated Fields

Summary: For any dataset, you can add a new field that is calculated based on a formula. This expands the scope of analyses and computations that you can do on your data.

Note: You can see a list of all available formula functions here.

Adding a calculated field to a dataset

To add a field, follow the below steps

1- In the Datasets list page, click edit next to the dataset for which you would like to add a new field

Edit Dataset

2- Click on the Fields Settings tab

3-Click on “Add new Field”

4-In the popup , fill the name of this new field and in the text area, write the formula used to calculate its value. Note that the autocomplete menu will show you any functions or columns that you can use in the formula. For example, let’s say we would like to add a new field that calculates the costs as : Cost= Sales-Profit. In this case we would add the new field “Cost”, and write its formula. By typing “S” , you can select the Sales field from the menu. The functions used are all based on Mysql native functions. You can see a list of all available functions here.

Now the field is ready to be used in the explore page, just like any other column:

Editing and Deleting Calculated Fields

You can edit or delete any calculated field from the fields list page, by clicking on the edit or delete icon. The edit will open the field popup where you will be able to amend its name or formula. The delete icon will delete the field from the dataset
