TriBar

A colleague was conducting a study in which he wanted respondents to apportion their respones into three categories. I wrote this simple applet to provide a novel visual approach to collecting such responses. Suppose, for example, you were asked to apportion the total ATI Workshop time into three categories:
  • Basic html and javascript for designing web pages (blue bar)
  • cgi and perl for collecting and reorganizing data from web pages (yellow bar)
  • Java for constructing applets for experiments (red bar)
Use your mouse to drag the boundaries of the bars below so that they represent your ideal allocation of workshop time into the three categories.

The Java source code for this simple applet is heavily commented to make it easy to follow.
