Steps To Making A Line Graph

What are the steps in making a line graph?


Answer:

Dee Reavis

Here are the steps to make a line graph:

1. Gather your data: Your data must be paired data. e.g. cost/month, price vs time.

2. Assign Values to your axes: You will need to assign values to your x axis (horizontal) and your y axis (vertical). e.g. cost -> y axis and months -> x axis.

3. Plot your data points: You must take each data point and place it on your graph paper (or electronic version of graph paper). e.g. assume that your first data pint is (2,4). The first number is always the x point, so you would go vertical from that spot on the x axis. Then find the 4 on the y axis and go horizontal from there. Where your vertical and horizontal meet is where you make a mark on your graph.

4. Connect the dots: Draw a line between the data points that you have plotted to finish making your line graph.

Line graph

Hello,
I have line graph that represents the number of years of a schools existence vs the number of computers purchased each year. The first point of the graph starts at (1, 50) as opposed to (0, 50) Why does it start at 50 not zero
Thanks.

Line Graph Construction
by: Dee Reavis

A line graph is usually constructed from the data on hand. In your example there was apparently no computers in year 0 or the start year. In year one there were 50 computers purchased. In this case the (0,0) point is assumed. Your graph could easily be extended to the (0,0) point and it would be equally as correct as the one you have.

Labeling Your Line Graph
by: Dee Reavis

Your line graph labels are the things that you want to compare. Quantity and time are the most common, but you can use anything.

If you want to see how the price of something changed over time, then time and quantity are your choice for axis labels.

If you wanted to know how much flour to use to make cookies for any number of people, you could just multiply it out. You could also create a line graph that you could refer to. You would just decide how many people you want to make cookies for and refer to your graph to find out how much flour you would need. The graph labels for the axes would be number of cookies and amount of flour.

Double Line Graphs
by: Dee Reavis

If you are familiar with single line graphs, you know that you can plot some variable against time or another variable. For example you might want to see the number of students attending your favorite university for each of the last 10 years.

Now if you can plot one line on a graph, you can plot more than one or many. You could plot on the same graph as above, the number of female student and the number of male students for each of the last 10 years.

Your result would not be a double line graph, but a triple line graph.

Line Graph

How do you start your graph? Do you highlight and copy into a graph or what?

Answer

I have included a short video on the Make A Line Graph page that shows how to use it. Basically you can change any of the numbers that are in boxes.
