Column Chart: It is usually used to display the
data in the form of vertical bars. It is used to
show the changes in data over a period of time
or for comparison among the different data
items. The categories are represented on the
horizontal axis, and the values are represented
on the vertical axis.
Pie Chart: It is a circular chart divided into sectors where
each sector shows the relative size of each value. It always
shows only one data series. It is useful when you want to
put emphasis on a significant element.
Bar Chart: The bar chart displays the data in
the form of long rectangular rods, also called
bars. These bars can be placed horizontally on
the chart area. It illustrates the comparisons
among the individual items. In this chart,
categories are represented on the vertical axis
and values are represented on the horizontal
axis.
Area Chart: It is used to display the quantitative
magnitude of the data graphically. These charts
are based on the features of the line chart.
They basically emphasise the area between the
line and the axis with the help of the colours,
textures, pictures, etc.
