Short description:

Apply a normalization factor to some columns based on their name.


Long Description:

Let’s assume that you have a table where each row represents a week and the columns contain the sales for each different day of the week. We want to normalize this dataset so that the value “1” represents the average normal sales on a given day of the week.

We’ll have:




The pin 0 of the ANATEL~3_img645 Normalize Action is connected to the dataset to normalize.



The pin 1 of the ANATEL~3_img645 Normalize Action is connected to a table with two columns. The first column contains the name of the columns to normalize. The second column contains the normalization factors. For example, in the above Anatella graph, we have:
