Replacing empty values in a column

You can easily replace empty values in your data within the Spotfire clients.

Prerequisites

You must have data with at least one missing value loaded in the analysis and the analysis must be in Editing mode.
Tip: You can also handle empty values by replacing the values directly in a table visualization.

Procedure

  1. On the authoring bar, click Data in analysis and click on the column of interest.
  2. In the expanded flyout, make sure that Details on selected column is selected.
  3. In the expanded flyout, locate the Empty values section.
  4. Under Replace empty values with, select one of the options.

    Value immediately before Replaces empty values with the first valid value that comes immediately before the missing value in the original data.

    Immediately following value Replaces empty values with the first valid value that comes immediately after the missing value in the original data.

    Average value Replaces empty values with the average value of the other values in the column. For integer values, the average is rounded towards zero when needed.

    Replace empty values with average example.

    Tip: If you want to avoid rounding of the average value you can change the data type of the column to Real before replacing the empty value .
    Median value Replaces empty values with the median value of the other values in the column. For integer values, a calculated median is rounded towards zero when needed.

    Replace empty values with median example.

    Tip: If you want to avoid rounding of the median value you can change the data type of the column to Real before replacing the empty value .
