    Add a method in Graphics(Class)

     

    void parmStacked(int _stacked = 0)
    {
        ;
        chartFXCtrl.stacked(_stacked);

    }

    Add a ActiveX(Chart Object) in a Form and set name="MyGraphics" and Add a method in Form

    and override TablePage method : pageActivated(element.showGraphics())

    void showGraphics()
    {
        AAATestGraphics       TestGraphics;
        Integer     mark;
        Integer     x;

        str         s;
        str         strPeriod;
        str         strKey;
        str         strBase;

        Map         mapPeriod   = new Map(Types::String,Types::String);
        Map         mapKey      = new Map(Types::String,Types::String);
        Map         mapBase     = new Map(Types::String,Types::Real);

        MapIterator mi;
        ;

        if (graphics)
            graphics.closeGraph();

        graphics = Graphics::newGraphicsNoTitles(Mygraphics,Mygraphics.widthValue() ? Mygraphics.widthValue() : 700,Mygraphics.heightValue() ? Mygraphics.heightValue() : 400);

        TestGraphics = AAATestGraphics_ds.getFirst(1,false);
        mark = 0;
    //    mark = 1;

        graphics.resetGraph();
        graphics.parmStacked(1);
        TestGraphics = AAATestGraphics_ds.getFirst(mark,true);
        while (TestGraphics)
        {
            x++;

            strPeriod   = TestGraphics.Month;
            strKey      = TestGraphics.Type;
            strBase     = num2str(TestGraphics.Value,1,2,1,0);

            if ( ! strPeriod && ! strKey && ! strBase)
                break;

            s =strPeriod+'#'+strKey+'#'+strBase+'#'+int2str(x);

            mapPeriod.insert(s,strPeriod);
            mapKey.insert(s,strKey);
            mapBase.insert(s,TestGraphics.Value);

            TestGraphics = AAATestGraphics_ds.getNext();
        }

            strKey      = mapKey.lookup(mi.key())    ? mapKey.lookup(mi.key())      : '\'\'';

            graphics.loadData(strPeriod,strKey,mapBase.lookup(mi.key()));

            mi.next();
