actions.

Learn how to Assemble a Bar Graph?

Steps
in development
of bar graphs/column graph:

● On a graph, draw two
strains perpendicular to one another, intersecting at 0.

● The horizontal line is
x-axis and vertical line is y-axis.

● Alongside the horizontal
axis, select the uniform width of bars and uniform hole between the
bars and write the names of the information objects whose values are to be marked.

● Alongside the vertical axis,
select an appropriate scale with a purpose to decide the heights of
the bars for the given values. (Frequency is taken alongside y-axis).

● Calculate the heights of
the bars in response to the dimensions chosen and draw the bars.

Bar graph provides the data of the
variety of youngsters concerned in several actions.

Solved examples on development of bar graphs:
