Stacked Column Chart, also referred to as Vertical Stacked Bar Chart, is formed by stacking one data-series on top of the another. The below example shows PHP Stacked Column Chart along with source code that you can try running locally.

Chart Customizations

The readability of the chart can be enhanced by enabling legends of data-series. You can do so by setting showInLegend to true at data-series level. Other commonly used customization options include setting color, showInLegend, etc.
