     * Creates a Bar Chart. A Bar Chart is a useful visualization technique to display quantitative information for
     * different categories that can show some progression (or regression) in the dataset. As with all other series, the Bar
     * Series must be appended in the *series* Chart array configuration. See the Chart documentation for more information.
     * A typical configuration object for the bar series could be:

     * to display the information found in the `data1` property of each element store, to render a formated text with the
     * `Ext.util.Format` we pass in, to have an `horizontal` orientation (as opposed to a vertical one) and we also set
     * other styles like `color`, `text-anchor`, etc.
