Bar graph vs line graph

Bar Graph Vs Line Graph. Bar graphs show data with blocks of different lengths whereas line graphs show a series of points connected by straight lines. A line graph is helpful for data over time and a bar graph is helpful for categories. This leads to a very different appearance but the biggest difference is that bar graphs are more versatile while line graphs are better for showing trends over time or another measure with a logical progression of values such as distance from a given point. The height of the bar corresponds to the value of the data.

Bar graphs are used to compare facts. For this example time is continuous in the line graph. All bars have a common base. Line graphs allow us to see overall trends such as an increase or decrease in data over time. When smaller changes exist line graphs are better to use than bar graphs. Basic graphs with discrete x-axis.

Draw two perpendicular lines intersecting each other at a point O.

Create an instructor-led experience where slides and multimedia are combined with quiz and poll questions. For this example time is continuous in the line graph. Line graphs are best for plotting points over time. A line graph is helpful for data over time and a bar graph is helpful for categories. Properties of Bar Graphs. Line graphs are used to display data or information that changes continuously over time.
