How Do I Use This Activity?

This activity allows the user to graph data sets in bar graphs. The color, thickness and scale of the graph are adjustable. Users may input their own data, or use or alter pre-made data sets.

This Java applet requires a Java-capable browser. If you don't see the applet Java may not be functional in your browser or on your machine.

Controls and Outputs

• Pre-made data sets may be selected from a choice menu. To alter the data, the user may change the data displayed in the data box below the choice menu, and hit the "Graph Data" button. To clear all data, the user may hit the "Clear Data" button. The choice menu, data box with data, and the two buttons are shown below.
