Detailed Description

This class handles 1D plots of data using Qwt.

Author:: Shekhar S. Chandra, 2008-2009

It handles multiple 1D plots on the same plot and uses a generated scale and legend.

Usage Example 1:

    DGVPlot *rowPlot = new DGVPlot;
    Array<double,1> uniqueRow(prime), op(prime);
    firstIndex x;
    int prime = 13;

    uniqueRow = sin(4.0*x/prime);

    op = x;
    rowPlot->setName("Nth Ghost");
    rowPlot->createCurvePlot(op,uniqueRow,"Nth Ghost");
    rowPlot->show();

Usage Example 2:

    DGVPlot *rowPlot = new DGVPlot;
    Array<double,1> uniqueRow(prime), op(prime);
    firstIndex x;
    int prime = 13;

    uniqueRow = sin(4.0*x/prime);

    op = x;
    rowPlot->setName("Nth Ghost");
    rowPlot->setData(op,uniqueRow);
    rowPlot->generatePlot();
    rowPlot->show();

If memory conscious, use example 1 instead of example 2.
