Creating a Line Graph
Slide 1
This is a step by step guide to creating a
line graph
A step by step guide
Using the following data we will show how to draw a line
graph.

It is normal to place the variable quantity, in this case the
temperature, on the y-axis.
Notice that the temperature ranges from -10 oC to 23 oC, this
means that we will have to draw the y-axis to include negative
values

Lastly, add a title
The

a cross.
Now you try an example
data,
draw a line to connect
the points
As we have seen previously, we first
need to draw vertical and horizontal
axes, and insert the scales, in this
case there are negative quantities, we
therefore need to extend the y-axis
below the line of the x-axis

We will be creating a line graph of this
data.
It is normal to place the variable
quantity, in this case the temperature,
on the y-axis.
Notice that the temperature ranges
from -10 oC to 23 oC, this means that
we will have to draw the y-axis to
include negative values
As we have seen previously, we first
need to draw vertical and horizontal
axes, and insert the scales, in this case
there are negative quantities, we
therefore need to extend the y-axis
below the line of the x-axis
Next we add the x and y axes labels
The first co-ordinate is at zero seconds
and the temperature is -10oC (0,-10),
let’s mark it with a cross.
The second co-ordinate is 10,-5, again
we will mark it with a cross.
Now repeat for all the other data, and
draw a line to connect the points.
