A horizontal bar graph is a visual representation of data that include a series of horizontal bars representing numerical amounts. Variations in the lengths of the bars allows for quick comparisons. More »

A double bar graph is a chart that uses parallel bars at proportional lengths that represent quantitative values. The length of the bar correlates with the data. More »

To find the mean, range and mode on a bar graph, analyze both the x- and y-axis. The mode on a bar graph is the value that has the highest bar while the range refers to the difference between the highest and lowest value... More »

A broken axis graph is one in which part of the scale on the x or y axis has been omitted to save space. The broken axis graph has a wavy line at the location where the scale is broken. More »

Several types of graphs are used for displaying information in mathematics including the bar graph; pie chart or circle graph; histogram; stem and leaf plot; dot plot; scatter plot; and time-series graphs. The type of gr... More »
