What is the importance of charts and graphics in providing information from Nios?
Vertical line graphs are graphs in which a vertical line extends from each data point down to the horizontal axis. Vertical line graph sometimes also called a column graph. A line parallel to the y-axis is called a vertical line. Show
Horizontal Line GraphHorizontal line graphs are graphs in which a horizontal line extends from each data point parallel to the earth. Horizontal line graph sometimes also called a row graph. A line parallel to the x-axis is called a vertical line Straight Line GraphA line graph is a graph formed by segments of straight lines that join the plotted points that represent given data. The line graph is used to solve changing conditions, often over a certain time interval. A general linear function has the form y = mx + c, where m and c are constants. The fundamental rule at the rear of sketching a linear graph is that we require only two points to graph a straight line. The subsequent procedure is followed in drawing linear graphs:
Different Parts of Line GraphTitle: The title explains what graph is to be plotted. Scale: The scale is the numbers that explain the units utilized on the linear graph. Labels: Both the side and the bottom of the linear graph have a label that indicates what kind of data is represented in the graph. X-axis describes the data points on the line and the y-axis shows the numeric value for each point on the line. Bars: They measure the data number. Data values: they are the actual numbers for each data point. How to Make a Line Graph?If we have created data tables, then we draw linear graphs using the data tables. These graphs are plotted as a series of points, which are later joined with straight lines to provide a simple way to review data collected over time. It offers an excellent visual format of the outcome data collected over time. To plot a linear/line graph follow the below steps:
Double Line GraphA double line graph is a line graph with two lines. A graph that compares two different subjects over a period of time. A double line graph shows how things change over a period of time. The double line graph shows two line graphs within one chart. Double line graphs are used to compare trends and patterns between two subjects. Steps to Make a Double Line Graph:
Example: See the graph below. The points on the double line graph show the average monthly rainfall in the two cities (city 1, city 2). The separate lines that are made by connecting the points for each city. Uses of Line GraphThe important use of line graph is to track the changes over the short and long period of time. It is also used to compare the changes over the same period of time for different groups. It is always better to use the line than the bar graph, whenever the small changes exist. For example, in a company finance team wants to plot the changes in the cash amount that the company has on hand over time. In that case, they use the line graph plotting the points over the horizontal and the vertical axis. It usually represents the time period of the data. Line Graph ExampleQuestion: Sketch the solution on number line |x + 2| ≤ 5. Solution: Given, inequality |x + 2| ≤ 5 Step 1: Change the inequality into a compound inequality – 5 ≤ x + 2 ≤ 5 Step 2: Subtract 2 from all three sides to get – 5 – 2 ≤ x + 2 – 2 ≤ 5 – 2 = – 7 ≤ x ≤ 3 Step 3: Place this value on a number line To learn different types of graphs used in Statistics, register with BYJU’S – The Learning App and download the app to get Maths-related videos. Frequently Asked Questions – FAQsGenerally, line graphs or line charts are used to track variations over time, which may be long-term or short-term. We can also use line graphs to compare changes over the same period for more than one group. To make a linear/line graph, follow the below steps: A line graph helps understand the performance or comparisons over time by observing the line’s steepness on a graph sheet. The five major parts of a line graph include the following: It is essential to know that all line graphs must have a title part. A line graph possesses two axes, namely x and y. The events and the categories required to compare for a given time should be taken on the x-axis of a line graph. The y-axis describes the scale, which expresses the data and is organized into regular intervals. |
