WHAT IS A CHART GRAPH?
A chart/graph
is a graphical or visual representation of a

Line Graph
- graph in which the dependent variable is continuous. The Pointsare plotted using x- and y-components. The points are connected
because the observations are NOT independent. (the next valuedepends on the previous value)

Pie Graph
- graph in which the dependent variable is NOT continuous. It
usually presents data as a part of a whole or as percentages.

Histograms
- A specific type of bar graph. The graph in which the dependentvariable must have a natural order that can be grouped into defined
chunks. The bars must always touch. The Y-axis is usually apercentage or a frequency (count).

Scatter Plots
-graph in which the dependent variable is continuous. The
points are plotted using x- and y-components. The points are NOT
connected because the observations are independent (the nextvalue does NOT depend on the previous value). It uses a best-fit line
or curve to show relationship.

PROCEDURES IN
CONSTRUCTING A
GRAPH CHART ON MS EXCEL
Steps:
1. Enter information into a spreadsheet. Columns will be vertical
on the graph and rows will be horizontal.

4. Choose the kind of graph you want to use. Your choice largely
depends on what youll be using the graph for and what kind of
information you have. To compare how things have changed over
time, a line graph may be ideal. To display growth, a bar or column
graph works nicely. Evaluate your information and how you want
to present it.

5. At this point, you have a basic chart. Now its time to spruce it
up a bit. Add a title by clicking the Chart Title box at the top. You
can change the colors using the options at the top, name each axis,
and move or change the legend, which is located at the bottom.
The goal is simply to make it very clear to read. A good graph is
useless if it cant be understood easily.
