Bar graphs are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars are proportional to the measure of data. Horizontal bars are comfortable to read since the structure mimics how we process information (in western cultures), where we read from left to right, starting at the top. Our eyes start at the base and scan towards the end of each bar. Use a zero-baseline. This type of bar graph is typically referred to as a horizontal bar graph.

There is no specific rule here, but generally speaking, the gap should be thinner than the width of the bars. We measure the lengths relative to both the baseline and the other bars, so it's a straightforward process to identify the smallest or the largest bar. An example would be a representation of the number of males in grades 4-6 for each of the years 1995 to 2010. Move direct data labels inside bars. The actual number (discrete value) could be represented by a bar sized to scale, with the scale appearing on the X-axis. We believe it’s important to take an occasional pulse on foundational knowledge, regardless of where you are in your learning journey. The dependent variable may be discrete or continuous. Bar graphs can show trends over time (as in the previous example), but line graphs have an advantage in that itâs easier to see small changes on line graphs than bar graphs, and that the line makes the overall trends very clear. Use a bar graph when you want to show how different things compare in terms of size or value. A bar chart uses bars to show comparisons between categories of data.
