When do use line graph

This is important because the area of each bar implies volume. On a line graph, we plot individual points on the two axes and join them with straight lines. The vertical axis can represent any kind of value. The horizontal axis, however, should almost always represent time or some quantity that increases sequentially like distance, age, stage of a project, etc. Line graphs are especially good at illustrating changes and trends. The lines between the individual points help us understand how those points change.

In the image above, for example, the red line shows that the percentage of U. The decrease is too slight to see if we were looking at non-visualized data points in a table, but the line graph illuminates the trend. Furthermore, line graphs are adept at showing numerous quantities over time by using multiple lines. This is great if you want to compare the change in one category versus the change in other categories.

Line graphs are best used when you want to show changes over time. They are less versatile than bar graphs because one axis has to be time , but their ability to show the direction of trends is unparalleled, especially when the changes are slight.

When you choose a type of graph to display your data, the best solution is the one that accurately conveys the information.

Line graphs are best for plotting points over time. Bar graphs are best for comparing distinct categories. There are always exceptions. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

Area graphs are very similar to line graphs. They can be used to track changes over time for one or more groups. Line graphs use data point "markers," which are connected by straight lines. These data points, connected by straight lines, aid in visualization. While line graphs are used across many different fields for different purposes, they are especially helpful when it is necessary to create a graphical depiction of changes in values over time. Line graphs are often used in finance to create visual representations of values over time, including changes in the prices of securities , company revenue sheets, and histories of major stock indexes.

They are also useful for comparing different securities. In investing, specifically with respect to the field of technical analysis , line graphs are used by investors to visualize trends, which can greatly aid them in their analyses.

There are some limitations to line graphs. For example, line graphs often lose clarity when there are too many data points. It is also easy to manipulate them visually in order to achieve certain effects. For example, the apparent degree of change can be visually manipulated by adjusting the range of data points on the axes. Line graphs can be constructed manually, or by using software, such as Microsoft Excel, which greatly improves the speed, and accuracy, of the end product.

Line graphs consist of two axes: x-axis horizontal and y-axis vertical. Each axis represents a different data type, and the points at which they intersect is 0,0.

The x-axis is the independent axis because its values are not dependent on anything measured. The y-axis is the dependent axis because its values depend on the x-axis's values.

Each axis should be labeled according to the data measured along that axis. Then, each axis should be divided in appropriate increments e. For example, if measuring the changes in a stock's prices for the previous two weeks, the x-axis would represent the time measured trading days within the period , and the y-axis would represent stock prices. When using line graphs to track the price of a stock, the data point most commonly used is the closing price of the stock.

Each data point is plotted and connected by a line that visually shows the changes in the values over time. If the value of the stock increased daily, the line would slope upward and to the right. Conversely, if the price of the stock was steadily decreasing, then the line would slope downward and to the right. Line graphs are used to track changes over different periods of time. Line graphs can also be used as a tool for comparison: to compare changes over the same period of time for more than one group.

A line graph is a graphical display of information that changes continuously over time. Within a line graph, there are various data points connected together by a straight line that reveals a continuous change in the values represented by the data points. Line graphs are useful in finance because they are very effective at creating visual representations of trends over time.

For this reason, they are often used to depict how a stock is performing over a specific period of time. Graph theory is a mathematical discipline. Graph theory specifically studies graphs, mathematical structures that are used to model pairwise relations between objects. In graph theory, a line graph is also called a covering graph, the derivative, the edge-to-vertex dual, the conjugate, the representative graph, the edge graph, the interchange graph, the adjoint graph, and the derived graph.

This is the formal definition of a line graph: Given a graph G , its line graph L G is a graph such that each vertex of L G represents an edge of G, and two vertices of L G are adjacent if their corresponding edges share a common endpoint in G. A line graph is the intersection graph of the edges of G , representing each edge by the set of its two endpoints.
