Introduction

Filtering commonly augments data displaying functionality. Users can create multiple views of a single data set based on different filter criteria. As data sets become larger and larger, filtering also helps increase performance and improve usability by reducing the information shown. Take Excel for example. After filtering is enabled, each column header will include a button, when clicked, displays the filtering configuration dialog box for the respective column. Users can then edit the condition that the data in that column must satisfy in order to be included in the final display. In this smalltalk, I am going to create a user interface similar to Excel for collecting filtering criteria, and use that information in an application to perform the actual filtering operation.

Live Demo

As an example, law enforcement agencies can use filtering to find trends in criminal activities. For concreteness, criminal records were taken from Sacramento in 2006 [1], which consists of 7,584 offenses. It is also interesting to mark illegal occurrences on google maps.
