Final answer:
To convert a regular column chart to a stacked column chart, you would need to modify the chart settings and change the chart type to a stacked column chart.
Step-by-step explanation:
To convert a regular column chart to a stacked column chart, you would need to modify the chart settings in the software you are using to create the chart. In most software, this can be done by selecting the chart and changing the chart type to a stacked column chart. This will group the columns together, with each column representing a category, and the stacked columns showing the subcategories within each category.
For example, if you have a regular column chart showing sales data for different products, you can convert it to a stacked column chart to show the sales data for each product category.
To do this in Microsoft Excel, you would select the chart, go to the 'Design' tab in the Chart Tools menu, click on the 'Change Chart Type' button, and select the 'Stacked Column' chart type.
