in finance, line graphs are commonly used to depict the historical price action of an asset or security. each axis represents a different data type, and the points at which they intersect is (0,0). each data point is plotted and connected by a line that visually shows the changes in the values over time. a simple line graph is the most basic type of line graph.

a compound line graph uses multiple variables similar to a multiple line graph. each item of data on a line graph is a reference to a different source that ties the dependent variable to an independent variable. in most line graphs, the x-axis will be related to time, whether it is the different months in a year or the number of weeks that have passed since a product launch. depending on the underlying data, a line graph is best for: line graphs are used to track changes over different periods of time. the data points for each dependent variable are marked on the graph are connected by a line.

## line graph format

a line graph sample is a type of document that creates a copy of itself when you open it. The doc or excel template has all of the design and format of the line graph sample, such as logos and tables, but you can modify content without altering the original style. When designing line graph form, you may add related information such as line graph maker,line graph ielts,line graph x and y-axis,line graph example,line graph examples with explanation

when designing line graph example, it is important to consider related questions or ideas, what is a line graph? how do you draw a line graph in math? what is a line graph to describe? what are the 5 types of line graphs?, line graph in graph theory,simple line graph,line graph in excel,parts of a line graph,what is a line graph used for

when designing the line graph document, it is also essential to consider the different formats such as Word, pdf, Excel, ppt, doc etc, you may also add related information such as double line graph,compound line graph,multiple line graph,bar graph

## line graph guide

a line graph is a unique graph which is commonly used in statistics. this variation is usually plotted in a two-dimensional xy plane. thus, the line graph is also called a linear graph. a line graph or line chart or line plot is a graph that utilizes points and lines to represent change over time. it is a chart that shows a line joining several points or a line that shows the relation between the points. vertical line graphs are graphs in which a vertical line extends from each data point down to the horizontal axis. a line parallel to the y-axis is called a vertical line. horizontal line graphs are graphs in which a horizontal line extends from each data point parallel to the earth. the line graph is used to solve changing conditions, often over a certain time interval.

the fundamental rule at the rear of sketching a linear graph is that we require only two points to graph a straight line. the subsequent procedure is followed in drawing linear graphs: labels: both the side and the bottom of the linear graph have a label that indicates what kind of data is represented in the graph. these graphs are plotted as a series of points, which are later joined with straight lines to provide a simple way to review data collected over time. a double line graph is a line graph with two lines. a double line graph shows how things change over a period of time. the double line graph shows two line graphs within one chart. the points on the double line graph show the average monthly rainfall in the two cities (city 1, city 2). the important use of line graph is to track the changes over the short and long period of time. for example, in a company finance team wants to plot the changes in the cash amount that the company has on hand over time. in that case, they use the line graph plotting the points over the horizontal and the vertical axis.

line graphs are good for plotting data that has peaks (ups) and valleys (downs), or that was collected in a short time period. the title offers a short explanation of what is in your graph. it can be creative or simple as long as it tells what is in the graph. the title of this graph tells the reader that the graph contains information about the changes in money spent on students of elementary and secondary schools from 1961 to 2002. the legend tells what each line represents. the source explains where you found the information that is in your graph.

in this graph, the source tells us that we found our information from nces. in line graphs, the y-axis runs vertically (up and down). in this line graph, the y-axis is measuring the amount of money spent on individual students for public education. the most important part of your graph is the information, or data, it contains. in line graphs, like the one above, the x-axis runs horizontally (flat). in this line graph, the x-axis measured different school years.

the line graph has an x-axis and a y-axis. line graph helps to analyze the trend of whether the quantity in the y-axis is increasing or decreasing over a period of time. the line segment connecting these individual data points gives a picture of whether the sale of bicycles is in an increasing or decreasing trend. the result is that the straight line always progresses in a horizontal fashion and for each x value, there is a unique value of y. for example, the company cannot have two different value sales at the same time.

graph a is a line graph whereas graph b is called the scattered graph or scatter plot. an example of a line graph would be to record the temperature of a city for all the days of a week to analyze the increasing or decreasing trend. the point of intersection on the line graph that matches a time on the x-axis to a data value on the y-axis is called a data point. there can be more than one line in a line graph as it helps to compare the data.

each vertex of the line graph is shown labeled with the pair of endpoints of the corresponding edge in the original graph. in the illustration of the diamond graph shown, rotating the graph by 90 degrees is not a symmetry of the graph, but is a symmetry of its line graph. [24] for an arbitrary graph g, and an arbitrary vertex v in g, the set of edges incident to v corresponds to a clique in the line graph l(g).

[20] it is the line graph of a graph (rather than a multigraph) if this set of cliques satisfies the additional condition that no two vertices of l are both in the same two cliques. for connected graphs that are not paths, all sufficiently high numbers of iteration of the line graph operation produce graphs that are hamiltonian. for instance a complete bipartite graph k1,n has the same line graph as the dipole graph and shannon multigraph with the same number of edges. [38] for instance if edges d and e in the graph g are incident at a vertex v with degree k, then in the line graph l(g) the edge connecting the two vertices d and e can be given weight 1/(k − 1).
