WPLOT is a Windows program that plots two and three-dimensional
data. Up to 250 sets of data can be plotted on the same 2-Dimensional
plot using either one or two vertical axes. There can be up to 16000
data points per data set. Each data set can be plotted as a line
plot, a smooth curve plot, a scatter plot, a step plot or a histogram.
Multiple data sets can also be plotted as a 3-Dimensional plot.
The plot can have linear or log axes with auto or manual scaling.
Two-Dimensional plots can also have cumulative normal probability
axes, error bars and descending as well as ascending axes. Data
can be fit by a smooth curve or a least squares polynomial or exponential.
The Fast Fourier Transform can be used to fit the data with a discrete
Fourier series and the magnitudes of the FFT coefficients can be
plotted. Mathematical transformations of the data can be performed
by entering equations that operate on one or more data sets. Functions
can be evaluated and plotted. An auxiliary program, WFIT, can fit
a nonlinear function to data and use WPLOT to plot the fit. This
