How To Read And Create A Line Graph: Everything About Line Graph?

A Line Graph
A Line Graph

Line graphs, also known as line charts, are used to depict statistical data gathered across a given subject and period. So, a line is more of a connecting point for the data. Measured values are insights gathered during a study or investigation. There is an x-axis and a y-axis in the line graph. Today’s modern world has become increasingly information-centric. Every aspect of our life makes use of statistics in some way. The tabular display of data is an excellent method for expressing it methodically. A line graph plots a linear combination using a line on an X-Y axis, whereas a scatter plot employs points to depict discrete types of data.

Definition Of A Line Graph

A line graph is a sort of chart or graph, used to display data that changes frequently. A line graph may be created by connecting many locations using horizontal lines.

Line Graph In Detail

A line graph is a graphical depiction of the changes that have happened during a particular period. A line graph has an x-axis that runs horizontally and a y-axis that runs vertically. The x-axis generally contains a period that we want to determine the levels of a certain product or item in the y-axis. A line graph may be used to examine yet if the quantity on the y-axis is rising or declining over time. A line graph depicts an increasing or declining trend.

Parts Of A Line Graph

Let’s look at the various components of a line graph.

  • Title: The title of the graph informs us what the graph is all about, i.e what information the graph depicts.
  • Labels: The horizontal axis across the bottom and the vertical label along the side indicate the type of data shown.
  • Scales: The horizontal scale at the bottom and the vertical scale down the side indicate how much or how many there are.
  • Points: The graph’s points or dots indicate the (x,y) coordinates or ordered pairs. A line graph may contain more than one data line. The independent variable is the data on the horizontal axis, while the dependent variable is the data on the y-axis.
  • Lines: Straight lines linking locations provide estimated values between them. 

Example Of A Line Graph

The line graph if made would depict the sales of motorbikes by a motorcycle brand from February to March. The time is represented by the x-axis, while the quantity of motorbikes purchased every month is represented by the y-axis. An information point is represented by the black spot on the graph. A data point on a line graph indicates the value or number that corresponds to a certain period in the x-axis. Take, for example, the number of motorbikes sold in February is 50. Similarly, 30 motorbikes were sold in March. Using the data point, we may analyze this data for every month. The line segment that connects these independent and dependent variables depicts whether motorbike sales are rising or declining.

Points To Be Noted Based On The Example:

  • A line graph is sometimes referred to as a line chart. It aids in determining the correlation between two data, with one data set constantly reliant on the other.
  • The far more crucial aspect in this situation is the area under the curve. The slope of a line mainly depicts the lean of the curve in a graph. It is useful when determining the amount of growth among any two successive points on a graph. As an example: The more the value difference between two successive points, the higher the slope will be.
  • A line graph is a type of graph that evolves as a sequence of data values linked by parallel lines on the x and y-axis.
  • These are useful for displaying information about variables and trends. Line charts may influence perceptions more about outcomes of data that have not yet been captured.    

Conclusion

The reader will have a better understanding of these graphs and their overall idea as a result of this study. If the learners become perplexed, they may seek the aid of Cuemath, an excellent online platform that allows them to discover new ways of engaging with the learners and utilizing more effective techniques to solve any difficulty in mathematics.
