What characteristic defines the default bar shape in a bar data type series?

The characteristic that defines the default bar shape in a bar data type series is determined by the selected chart style. This means that when you choose a specific style for your chart, the appearance of the bars—whether they're cylindrical, 2D, or even 3D—will be influenced by that choice. Different chart styles come with preset designs and visual features that modify how the data is presented, which offers flexibility and customization options for the user.

In various charting tools, such as Kinaxis RapidResponse, the ability to select from a range of chart styles allows developers to tailor the presentation of data to better suit their analytical needs and enhance visual clarity. As a result, the final appearance of the bars may vary depending on the selected style, making this option the correct one.
