The x-axis shows days, while a bar extending up from that day shows how much volume there was per the y-axis. D… We use bar graphs to compare various items or choices. The y-axis represents a set of numbers we are examining over that span of time. The discrete value, or the number of instances in which an individual has a certain trait, is displayed by varying the length of the bar. For example, if too large of a scale is chosen, then the data may appear insignificant—when in fact it could be very significant, but the scale doesn't allow for an appropriate comparison. Bar graphs have an x- and y-axis and can be used to showcase one, two, or many categories of data. Some graphs may also have a legend that specifies what various colors represent, such as in a stacked bar graph. Stacked bars require a legend or specific labeling to identify what the various or parts of the bar are showing.

Define bar graph. each vertex of L(G) represents an edge of G; and; two vertices of L(G) are adjacent if and only if their corresponding edges share a common endpoint ("are incident") in G.; That is, it is the intersection graph of the edges of G, representing each edge by the set of its two endpoints. Stacked bar graphs or composite bar graphs divide an aggregate total into parts. The bars drawn are of uniform width, and the variable quantity is represented on one of the axes. See if you can answer them: Now that you have moved through the whole lesson, you are able to recall and state the definition of a line graph, identify the features of a line graph, including the x-axis, y-axis, titles, labels, and line for discrete data points, construct your own line graph, and interpret results recorded on an existing line graph.
