BAR GRAPHS
- bar graphs is a chart that compares the relative amount
of items by using bars of equal width in varying lengths
- bar graphs can be vertical or horizontal
- can appear on both sides of the axis to indicate positive
and negative quantities.
- cannot represent exact quantities or provide
comparisons of quantities

PIE CHARTS
- is a circle graphs that uses various sized slice to
represent relative parts of the whole.
-used for presenting numerical data.
- good providing a quick visual impression of a particularitem.

PICTOGRAPHS
- is a variation of a bar graphs that used symbols instead
of bars to illustrate specific quantities of items
-shows the changes in particular items over a period of
time.- symbols should realistically correspond to the items.

How do we make a line graph?
y A line graph ALWAYS has a title!
y A line graph has two different
axissy A n axis is either the horizontal
line (called x) or the vertical line(called y) that form the base lines
of a graph.

X-axis AND Y-axis
y When you are making a line graph, the x-axis is always horizontal, and the y-axis is
always vertical.yThe x and y-axis usually starts with zero
on a line graph
y
It is important to make sure that theintervals on our y-axis are always equal.
y What do I mean by this?

INTERPRETING LINE GRAPHS
y When we are setting up a line graph, we need todecide what intervals we want to use.
y
If we are graphing the temperature f or a year, do we want to put 365 days on the graph, and 100diff erent temperatures?
y When we see a horizontal f lat line, that means
that there was no change during a specif ic timeperiod.

PLOTTING LINE GRAPHS
yWhen we are plotting a line graph, it is important toread what inf ormation is on each axis.
y There must be a label on each axis that describes
the inf ormation.y Much like a bar graph, we look at the x-axis f irst in
order to plot our points.
