Dry erase bar line graphs from OptiMA Inc. offer you a great dry erase writing surface and easy to follow ghost grid lines contrasted against bold printed axis lines along the left side and along the bottom of the boards.
Everybody sells XY axis boards but not everyone offers you a blow up of just one quadrant. Now you can easily create all kinds of bar charts, line graphs and more.
All of our line graph bar chart boards are made in the U.S.A. Select from a number of different formats or options including wall mounted boards, smaller hand held lap boards or roll up dry erase magnets.
Of course custom prints, headings and grids are available through customer service. Add a company or school logo. Create your own designs. We can do it all for you.
