# How To Use a Line Chart

A line chart is a graph that plots points connected by straight lines. The points are usually connected in chronological order, with the oldest data point on the left and the most recent data point on the right. The x-axis typically represents time, while the y-axis represents a numerical value.

### Choose the type of line chart you want to use.

A line chart is a graph that shows how a particular variable changes over time. There are different types of line charts, and each has its own advantages and disadvantages. The most important thing to consider when choosing a line chart is what you want to use it to show. The simplest type of line chart is a straight line graph. This type is used to show how a single variable changes over time. It is most useful for showing trends over a long period of time. A step line graph is similar to a straight line graph, but it communicates how a variable changes at discrete points in time. This type is most useful for showing changes in data that are not smooth or linear. A smoothed line graph is used to show how a variable changes over time, but it uses a mathematical algorithm to smooth out the data. This type is most useful for showing trends over a long period of time. A broken line graph is used to show how a variable changes over time, but it uses a series of lines to show the different data points. This type is most useful for comparing data from different time periods.

### Create a line chart to show your data.

To create a line chart, you’ll need to gather some data. You can use a spreadsheet program like Microsoft Excel or Google Sheets to create your chart, or you can use an online charting tool. Once you have your data, you’ll need to decide how to display it. Most line charts use two axes: the horizontal axis (or x-axis) and the vertical axis (or y-axis). The x-axis typically displays time, while the y-axis displays the value of the data.
