Line Chart
A line chart is a type of graph that displays data as a series of points connected by straight lines. Line charts are often used to show trends over time, but they can also be used to display relationships between variables.
Line charts typically have two axes: the horizontal (x) axis represents the independent variable, usually time or some other continuous variable, and the vertical (y) axis represents the dependent variable, which can be continuous or discrete. Each data point on the chart represents the value of the dependent variable at a specific point in time or for a specific value of the independent variable.
Line charts are useful for visualizing trends and patterns in data, and they are often used to identify changes in the data over time or to compare the behavior of different variables. They can also be used to show how different groups or categories within the data are related.
Line charts can be created using a variety of software tools, including Excel, R, Python, and many others. They are commonly used in fields such as finance, economics, engineering, and social sciences, but they can be applied to any area where data is being analyzed.
