A Stacked column chart is a straightforward way to visualize data, displaying each category as a column divided into stacked segments.
It is particularly useful for comparing a small number of categories, such as the distribution of respondents by gender or age, allowing differences and proportions to be seen at a glance.

Click the Add widget type icon and select Chart as the widget type. A message will appear indicating that the stacked column chart is the default chart.
After the widget has been saved, the chart type can be changed in the Basic settings panel. See the section below for more information.
