3 Types of Graphs

Introduction of graph:

          A graph is a chart or drawing that demonstrates the relationship among alternating objects. They are a diagram showing the relationship among numerical values or amounts. The mainly used graphs are bar graph, line graph, and circle graph. Graph that shows the data in a diagrammatic representation. So that it is very interesting for the learner for view and study.

3 Types of Graphs:

Let we see about three types graph with this example.

  • bar graph
  • line graph
  • circle graph

These types are explained one by one.

Line Graph:

       This types of graph is extremely used for demonstrating data or information that altered frequently more time. Line graph is also said to be line chart.

Example:

Let us take the population ratio. Population ratio is calculated for every ten years once. The table given below gives the analysis of the population ratio for 6 years, which is shown below. Draw the line graph for the table given below.

Solution:

 

line graph1

 

 

Explanation:

  • The above diagram shows the line graph. From this the year is denoted in horizontal axis and the population in % is denoted vertical axis.
  • The interval for x-axis is 10 year and the population percentage interval is 5.
  • Now, show the table that is for the year 1950 the corresponding percentage 62 is pointed as a dot in a graph it is placed among 60 and 65.
  • Until points all the table values the above step is repeated.
  • Now connect all the marked points by a line this gives the line graph.

Bar Graph:

       This type of graph is one of the graph type which effectively shows outcomes that are one time, that aren't continuous - specifically samplings for instance surveys, inventories, and etc,. A bar graph is obviously off with a series of lines called as grid lines. These lines typically mark off a numerical peak in the series of values on the axis or line.

Example:

Let us take one table values that is marks of 5 students, draw the bar graph for this data values.

Solution:

 

 

 

bar graph1

 

 

Explanation:

  • The above diagram shows the bar graph in which student name is denoted in x axis and the mark is denoted in y axis.
  • Now show the table, at first the name honey and the corresponding mark is drawn as a vertical bar.
  • This process is repeated until all the datas are plotted.

 

Circle Graph:

      If the circle is splitted into number of parts or segment then the graph is called circle graph. In this type of graph each part denotes the part of data.

Example:

Let us consider the example for who like the particular fruits which is shown in the below table as a percentage. Now draw the circle graph for these datas.
