Line graphs consist of two axes: x-axis (horizontal) and y-axis (vertical) . Each axis represents a different data type, and the points at which they intersect is (0,0). The x-axis is the independent axis because its values are not dependent on anything measured.
What are the 5 parts of a line graph?

- The Legend. The legend tells what each line represents. ...
- The Source. The source explains where you found the information that is in your graph. ...
- Y-Axis. ...
- The Data. ...
- X-Axis.
What are the 4 parts of a line graph?
Title: tells about the data for each line graph is plotted. x-axis : tells about labels on x-axis, which is generally time. Trend: We join the points to draw the graph. The intersection point of the label on the x-axis and y-axis tells about the trend.
What are the two types of line graph?
There are 3 main types of line graphs in statistics namely, a simple line graph, multiple line graph, and a compound line graph . Each of these graph types has different uses depending on the kind of data that is being evaluated.
What is the main purpose of a line graph?
Line graphs are used to track changes over short and long periods of time . When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
What are disadvantages of line graphs?
- Plotting too many lines over the graph makes it cluttered and confusing to read.
- A wide range of data is challenging to plot over a line graph.
- They are only ideal for representing data that have numerical values and total figures such as values of total rainfall in a month.
Where do you start a line graph?
First Step: Draw a line for your x axis and your y axis . Second Step: add axis labels and an axis scale. Third Step: After that, mark your data points. Fourth Step: Next draw a line through the data points.
What is an example of a line graph?
A line graph is usually used to show the change of information over a period of time. This means that the horizontal axis is usually a time scale, for example minutes, hours, days, months or years. Example: The table shows the daily earnings of a store for five days .
What is a straight line on a graph called?
The formal term to describe a straight line graph is linear , whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.
How will you interpret data in a line graph?
The horizontal label across the bottom and the vertical label along the side tells us what kinds of data is being shown. The horizontal scale across the bottom and the vertical scale along the side tell us how much or how many. The points or dots on the graph represents the x,y coordinates or ordered pairs.
What are the types of lines?
- Horizontal Lines.
- Vertical Lines.
- Parallel Lines.
- Perpendicular Lines.
What is the purpose of a line?
In graphics, a line can be described as a single point that continues for a distance, or as the connection between two points. The purpose of a line in graphics is to help the artist to communicate to the viewers what it is they are supposed to be seeing or taking notice of .
What is another name for a line graph?
A line graph—also known as a line plot or a line chart —is a graph that uses lines to connect individual data points.
How do you do a line graph?
To draw a line graph, first draw a horizontal and a vertical axis . Age should be plotted on the horizontal axis because it is independent. Height should be plotted on the vertical axis. Then look for the given data and plot a point for each pair of values.
When should you avoid a line graph?
- Line charts are a classic tool for visualizing time-varying data (e.g., days, weeks, months, years etc...). ...
- Showing trends in a variable over time for multiple categories (if the variable is measured the same way for all categories)
What are the pros and cons of a line graph?
Line graph: Advantage: It’s better for seeing the rate clearly . Disadvantage: It’s harder to compare.
