How to Analyze Double and Triple Line Graphs A line graph is a display of graphical information that shows a continuous change of data. The lines in the line graph can ascend or descend based on the data. The data points connect and form a line graph. It is used to show comparison with situations, information, and events. Analyzing both double and triple graph needs comparisons. Unlike the triple line graph, double line graphs connect points to show a continuous change in data. Another point to focus is that the double line graph has two lines, and both can ascend and descend. The double line graph represents the two-axis, x-axis, and y-axis. The X-axis shows the occurrence and the categories that are compared over time and y-axis represents the scale. The scale comprises a set of numbers that represents the data and is organized at equal intervals. Unlike the double line graph, the triple line graph doesn't require a title to give the general overview. All this doesn't happen in a triple line graph, which creates a distinguishing point and makes it easier to understand.

Many times we will run into situation where we have two separate data sets and we want to be able to understand the data, but also understand how they relatively relate. Under these circumstances we will place multiple lines on the line graph. Once we have the data displayed, in this way, it easy to understand and compare the value of the data sets individually or relative to one another. These worksheets explain how to work with double and triple line graphs. Students will learn how to read and compare double and triple line graphs in order to answer questions about different data sets.
