Instructions for Use

Bar Graph allows your child to create a bar graph using any data they wish.

Take a look at the bar graph, then change the data to alter the bar graph. Try altering the data values as well as the number scale for the y axis. How does the graph change when you change the scale?

Try creating a completely new graph selecting “My Data” under “Choose data set”, then enter numbers and labels into the data box and click the “Graph Data” button to view your graph. Alter the scale of your graph and explain how the graph changes.
