Which of these is NOT true about a bar chart?

The assertion that a bar chart cannot show as much information as a column chart is not true. Both bar charts and column charts are designed to represent categorical data, and their information-carrying capacity is fundamentally similar. A bar chart typically displays data with horizontal bars, while a column chart displays it with vertical bars. The distinction in orientation does not inherently limit the amount of information conveyed.

Moreover, both chart types are useful for comparing data across categories, and each can effectively present complex datasets, particularly when combined with features such as grouping, stacking, or using different colors to represent different datasets. Therefore, there is no intrinsic limitation in a bar chart's ability to display information relative to a column chart; they serve similar purposes and can be equally effective depending on the data being presented and the audience.
