Quick-Reference: Bar Charts and Line Graphs

Reading Bar Charts

1. Check the axes — identify what the x-axis and y-axis represent, including units and scale
2. Read values carefully — bars may not align exactly with gridlines; estimate to the nearest gridline
3. Stacked bars — the total is the top of the bar; individual segments are read by their height, not their position
4. Grouped bars — compare bars within each group and across groups

Reading Line Graphs

1. Identify each line — use the legend to distinguish between series
2. Read intersection points — where a line meets a vertical gridline is the data value
3. Trends — rising, falling, or flat; steeper slope = faster rate of change
4. Interpolation — estimate values between plotted points by reading the line
