Answer 1

Why do you need to change a chart? To better visualize and analyze data based on the specific purpose. To highlight different aspects of data, such as trends, proportions, or relationships. To make the chart more understandable and appealing for the target audience. How can a chart be changed? Select the existing chart. Right-click and choose the \textit{Change Chart Type} option. Select the desired chart type (e.g., Pie Chart, Line Chart, etc.) and confirm by clicking \textit{OK}. Modify chart elements like labels, legends, and colors as needed to suit the new chart type. Why is it easy to change a column chart to a pie chart? Both chart types use the same data structure: a single series with categories and values. Excel and similar tools allow seamless conversion between these chart types while preserving the data source. Column charts represent data with bars, while pie charts display the same data as slices of a circle to show proportions.
