A time-series plot is the best choice for displaying data over time, such as the number of households using online banking and/or online bill payment from 1995 to 2010. This type of plot shows how the variable changes over time and allows for quick identification of trends and patterns. Pie charts are not appropriate for time-series data, and bar charts may be difficult to read when there are many years of data. Stem-and-leaf displays are more appropriate for displaying individual values or smaller datasets.
