3: How to make a bar chart

Since you already know how to make a scatterplot, making bar chart will be a lot easier. Here is a comparison:

For a scatterplot For a barchart
Choose x and y Same!
Label x, y, and give a title Same! (except x usually has no “units”)
Decide minimum and maximum values for x and y Only for y
Decide distance for ticks Only for y
Make a legend Same
Add data, using dots. Use rectangles, not dots



That’s about it. Oh, make sure you spread out the x values nicely, and make your bars wide enough to see.
