Narrow your filter, zero in your data perspective

Working with data can sometimes be a daunting task. Luckily, CARTO Builder’s analysis interface makes it easier than ever to perform data transformation, such as filtering, like never before. Filtering a dataset by column value can be done in just a few simple steps directly from CARTO Builder’s layer list or by selecting “Analysis” from the layer view once a layer is selected.

In the “Add a new analysis” screen, you will notice a variety of methods for manipulating and analyzing data. By selecting “Transform” and then “Filter by column value,” we have added our first analysis node to the layer’s workflow. Filtering by column value works directly with the data to only render parameters specified by the user.

If you are working with numerical or date values, it is possible to select a range from the data and filter out the results within the range, or not, meeting the criteria in the query. For string data types, or columns containing letters, numbers, and/or symbols, the filter by column value analysis allows you to search isolate, and/or remove specific cell values.

To learn more about analysis in CARTO Builder, be sure to check out our Analyzing your data section of our documentation.

Happy Data Mapping!
