DIAGRAMMATIC presentation of data

1. DIAGRAMMATIC
PRESENTATION OF DATA
A STYLE OF ANALYSIS OR DESIGN THAT
RELIES PRIMARILY ON THE USE OF
DIAGRAMS .

2. MEANING:
• A diagrammatic representation of data is a visual depiction
that helps to illustrate and summarize information in a
graphical format. It presents complex data sets or relationships
between variables in a more accessible and understandable
manner.

3. BAR DIAGRAM
• DEFINITION: A bar diagram, also known as a bar chart or bar graph, is
a graphical representation of data using rectangular bars or columns.
Each bar represents a category or group, and the length or height of the
bar corresponds to the quantity or value of the data it represents. Bar
diagrams are commonly used to display and compare the values of
different categories or to show how a single category changes over time.

4. FEATURES OF BAR DIAGRAM
• The bars on a bar graph have equal width and interval spacing.
• Bars can run vertically or horizontally.
• Bars share the same starting point or base. The y-axis of a bar graph is
the side or vertical axis.
• The x-axis of a bar graph is the bottom or horizontal axis.

5. TYPES OF BAR DIAGRAM
• SIMPLE BAR DIAGRAM
• MULTIPLE BAR DIAGRAM
• COMPONENT BAR DIAGRAM
• PERCENTAGE BAR DIAGRAM
• DEVIATION BAR DIAGRAM

6. SIMPLE BAR DIAGRAM
• MEANING:
A simple bar diagram, also known as a
bar chart, is a graphical representation of
data using rectangular bars to illustrate
the values of different categories.

7. MULTIPLE BAR DIAGRAM
• MEANING:
A multiple bar graph is a graph that has
multiple bars for each category. A multiple
bar graph compares as many sets of data
you want. The process for creating a
multiple bar graph is just like creating any other
bar graph,only you will have more colors to
represent different sets of data.

8. COMPONENT BAR DIAGRAM
• MEANING:
Component bar diagrams are also called sub
diagrams that represent different components
of a single piece of data. Pie charts are also
used to represent a similar distribution of
data but it is a circular diagram, unlike a
component bar diagram which is rectangular.

9. PERCENTAGE BAR DIAGRAM
• MEANING:
A percentage bar diagram, also known as a
percentage bar chart, is a type of bar chart
that represents the composition or distribution
of a whole in terms of percentages. It is
particularly useful when you want to
illustrate the proportion of each category
relative to the total.

10. DEVIATION BAR DIAGRAM
• MEANING:
It seems there might be a confusion in terminology,
as "deviation bar diagram" is not a standard term
in data visualization. However, if you're referring
to a diagram that represents deviations or
variances from a certain baseline or average,
you might be thinking of something like
a "deviation bar chart" or a "variance bar chart."

11. PIE OR CIRCULAR DIAGRAM
• MEANING:
A pie chart, also known as a circular diagram, is a circular statistical
graphic that is divided into slices to illustrate numerical proportions. In a
pie chart, each slice represents a proportionate part of the whole. The
entire circle represents 100%, and each slice represents a percentage or
fraction of that total.

12. FEATURES OF PIE DIAGRAM
• Slices: The chart is divided into slices, each representing a portion or category
of the whole. The size of each slice corresponds to the proportion or percentage
it represents.
• Whole Circle: The entire circle represents the total or 100%. The combination
of all the slices adds up to the complete circle, emphasizing the relationship
between individual parts and the whole.
• Colors or Patterns: Different colors or patterns are often used to distinguish
between slices. This visual distinction aids in identifying and differentiating the
various categories.
