The 3 things i know about graphing are..
1.There is a title at the top of the graph to make sure the people you are showing the graph to know what the graph is about.
2.The intrevals on the side indicate on how much or how many one thing has depends on the number.
3.The labels must be on the x axis and the y axis to indicate what the intrevals on the y axis are and the number are the x axis are.
What I know now that would improve my test.
What i know now that would improve my test is that to do a bar graph instead of doing a double line graph.
