Plot Maestro is a plotting program but also allows you to plot graphs the old fashioned way using graph paper.
Students can now print their own graph paper.
Plot Maestro has full support for plotting data sets of x, y data pairs. The program can also calculate and plot the best fit curve to the data set using linear, exponential, logarithmic or power curve fits and will calculate the coefficient of determination. This allows the student to determine which method produces the best fit. Up to 10 different data sets may be plotted on the same chart. Plot Maestro may also plot any formula.
