OptiMA® 4 x 4 Dry Erase Line Graph Board

The large 4' X 4' dry erase line graph boards are an interesting alternative to the popular XY axis grid boards because the print focuses on a blow-up of only one quadrant versus a print of all four quadrants. There is a bold axis line on the left that intersects with another axis line that crosses the bottom. The 1" X 1" grid features darker or bolder lines every fifth row and column to make the graph easier to follow, plot, or read. The 1" X 1" grid provides a total of 40 rows and 40 columns. The print is covered in the exclusive clear dry erase writing surface so it is protected for the life of the board, which under proper care will last for years to come. Users have the option of a magnetic or a non-magnetic version; the magnetic version is slightly more expensive but gives the option of using magnetic accessories with the line graph. Both versions are made in the USA, and school purchase orders are gladly accepted. Any print can also be modified to user specifications for a small artwork fee.
