Which chart type is used to represent data that is consecutively measured over time?

A line chart is the most effective type for displaying continuous data measured over time. It connects individual data points with a line, which clearly illustrates trends, patterns, and fluctuations at equal intervals, such as days, months, or years. This visual connection between points emphasizes the progression and change in data values across a time period, making it the standard choice for time-series analysis.

A. Pie chart: This chart represents proportions of a whole at a single point in time and cannot show changes or trends over a period.

B. Column chart: While it can display data over time, it emphasizes the magnitude of individual data points rather than the continuous trend between them.

C. Bar chart: This is a horizontal version of a column chart, best used for comparing values across discrete categories, not for showing continuous time-series data.

"Line charts can display continuous data over time

set against a common scale

and are therefore ideal for showing trends in data at equal intervals."
