Bar Chart Tutorial

BRIDGES provides a basic set of bar charts for plotting information based on category grouping.

First one defines the category groupings with setCategories(). One can label the category axis with setCategoriesLabel(). When hovering on a bar, a tooltip will appear and one can add units to the values by using setTooltipSuffix().

One can have a single series of data to make a standard bar chart or multiple series of data to make a clustered bar chart. One specifies a data serie using addDataSeries() which takes the name of the series and an array of floats which provide the value of that serie for each of the category.

The BarChart can have a title (see getTitle() and setTitle()) and a subtitle (see setSubTitle() and getSubTitle()). The bars can be either vertical bars or horizontal bars using setBarOrientation()

This tutorial will illustrate the use of bar charts to display some population information (which is made up).
