Formulas for Line Chart

Types of Line Chart 

• Data Series: In a line chart, data is represented as a series of data points, where each data point corresponds to a specific value at a particular point in time or along a continuous scale. These data points are connected by straight lines to form the chart.

• X-Axis and Y-Axis: Line charts have two axes: the horizontal axis, known as the X-axis, and the vertical axis, known as the Y-axis. The X-axis typically represents the independent variable, such as time, while the Y-axis represents the dependent variable, which can be any numerical value.

• Data Points: Each data point on the chart consists of a pair of values: one for the X-coordinate (horizontal position) and one for the Y-coordinate (vertical position). The X-coordinate is used to determine where the data point is plotted along the X-axis, while the Y-coordinate determines its position along the Y-axis.

• Line Segments: The data points on the line chart are connected by line segments. These line segments provide a visual representation of the trend or pattern in the data. A continuous line typically suggests a smooth progression between data points.

• Trends and Patterns: Line charts are particularly useful for visualizing trends in data. An upward-sloping line indicates increasing values over time or along the X-axis, while a downward-sloping line suggests decreasing values. A horizontal line suggests no change, and fluctuations in the line can reveal patterns or cycles in the data.

• Title and Labels: A line chart typically includes a title and labels for both the X-axis and Y-axis to provide context and help the viewer understand the data being displayed.
