what is a line plot

A line plot is a type of graph that displays data as a series of data points called markers connected by straight line segments. It is also known as a dot plot. A line plot is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically. A line plot can be defined as a graph that displays data as points or check marks above a number line, showing the frequency of each value. To create a line plot, first create a number line that includes all the values in the data set. Next, place an X or other symbol above the number line for each data point. A line plot is a way to display data along a number line. It is a basic type of chart common in many fields.
