What is a broken line graph?

A:

Quick Answer

According to the Cambridge Dictionary, a broken line graph is "a graph that shows information as dots that are connected by straight lines." These graphs do not necessarily form an overall straight line. Each data point is often a vertex where the line makes a change in direction.

Full Answer

Broken line graphs are one way to show information. Users of these graphs often choose this method of representing changes in data over time, such as changes in stock market prices throughout a day or changes in daily temperatures. The lines allow users to interpolate unknown data values between two dots representing known values.

In such graphs, convention dictates one independent variable horizontally on the x-axis and the dependant variable vertically on the y-axis. Broken line graphs are also useful in presenting data collected over time when a third variable exists. An example includes a broken line graph showing monthly temperature averages for two different locations. The preparer uses different colors for the lines to represent each city, allowing graph users to easily compare trends that exist. While line graphs are simple to construct using graph paper and a ruler, a spreadsheet such as Excel allows users to construct professional-looking representations of data they collect.

    What is a bipartite graph?

    A:

    A bipartite graph, also known as a bigraph, refers to a graph whose vertex set can be divided into two independent sets. The division is done in such a way that each edge of the graph connects a vertex in the first set to a vertex in the second set.

    What is a segmented bar graph?

    A:

    A segmented bar graph is similar to regular bar graph except the bars are made of different segments that are represented visually through colored sections. A segmented bar graph is sometimes known as a stacked bar graph, and it offers greater detail about data sets.

    What is a continuous graph?

    A:

    A continuous graph is a graph that describes a space containing smoothly connected numerical values. There are no values excluded in between individual points on this graph. Continuous graphs are sometimes conflated with continuous functions, which are smoothly connected plot lines or shapes.
