Question

how to make a bar graph

Answer 1

draw an L shape and put dash marks along the bottom and side line to form your variable bottom (x) side (y) and plug your variables in EX. bottom would be hour segments and side would be how much TV's you sold in that hour. and you would draw a vertical bar going up and down for each hourly segment and fill it in based on how many you sold every hour.

Answer 2

Bar Graph

There are all kinds of charts and graphs, some are easy to understand while others can be pretty tricky. There are many different types because each one has a fairly specific use. Bar graphs can be used to show how something changes over time or to compare items. They have an x-axis (horizontal) and a y-axis (vertical). Typically, the x-axis has numbers for the time period or what is being measured, and the y-axis has numbers for the amount of stuff being measured. Bar graphs are good when you're plotting data that spans many years (or days, weeks...), has really big changes from year to year (or day to day...), or when you are comparing things.
