Frequently asked questions
Bar graph or line graph?
Use a bar graph to compare separate groups (like three types of light). Use a line graph when the X-axis is time or a number that goes up in steps.
How big should I print it?
For a tri-fold board, print the PNG on a full letter-size page in landscape so judges can read it from a few feet away.
