Line Chart

A line chart is a type of graph that displays information as a series of data points, called 'markers,' connected by straight line segments. It is commonly used to show trends and relationships over time.

Key Elements of a Line Chart

X-axis: The horizontal axis that represents the independent variable, such as time, categories, or other ordered data.
Y-axis: The vertical axis that represents the dependent variable, such as numerical values or counts.
Data Points: Individual points on the chart that represent specific values of the variables being measured.
Line: The line that connects the data points, showing the trend or pattern in the data.
Title and Labels: The chart should have a title and labels for the x-axis and y-axis to provide context and clarity.

How to Create a Line Chart

Collect Data: Gather the data points that you want to represent on the chart.
Choose the Variables: Determine which variable will be represented on the x-axis and which will be on the y-axis.
Scale the Axes: Determine the range and scale for each axis to best display the data.
Plot the Points: Plot each data point on the chart using the appropriate coordinates.
Connect the Points: Draw a line that connects the data points, showing the trend or pattern in the data.
Add Titles and Labels: Include a title and labels for the axes to provide context for the chart.
