no, that's why you label each side as you go.
You can use a bar graph when you are working with numers. :)
The difference between a bar graph and a double bar graph is...... A bar graph displays one set of data, and a double bar graph compares two different sets of information/data.So should have a key.
When you are explaining something that has to do with bar graphs.
It is the legend or key.
The graph key is to make sure everyone understands what things mean, like a map key
All graphs need labels or data on both of the axis to be of use. So all graphs require a "key"
I use a bar graph to represent my favorite pies, and a pie graph to represent my favorite bars.
BAR GRAPH!
anything you want to put in a bar graph
a picture graph uses pictures to show the point and bar graph use bar lines to show the point.
Every graph must have a key. Keys are to show which bit of the graph represent which data and what values are shown by the location or size or colour of the graph.
