Class WPlot



  • public class WPlotextends Object
    Canvas to plot various DMelt data. The canvas is based on the Waterfloo package. One can plot scatter, histogram, polar, pie charts, real-time charts. Also supports for X-Y data points with errors on X and Y. Built-in "click-and-edit" support and publication-quality output to vector-based graphics formats for printing.
