A line chart or line plot or line graph is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments. A line chart is often used to visualize a trend in data over intervals of time (a time series) thus the line is often drawn chronologically. In these cases they are known as run charts.
The Notebook here contains the code of line plots like the one shown below.
