A Bar chart is an inverted Column chart in the sense that the X and Y axes are reversed.

When a data set contains X or Y values which span a large range, sometimes the normal chart setup does not display the information most effectively. Formatting a chart with a vertical Y-axis and axis annotation that begins at the minimum value can sometimes be more visually appealing if the chart could be inverted. Therefore, C1BarChart provides the Horizontal property of the C1BarChart.

Setting the Horizontal property of the C1BarChart to False will revert the axes. This means that the Y-axis will take the place of the X-axis, and the X-axis will take the place of the Y-axis and the chart will appear as a Column chart.
