java - How to know the values of every DataSet on JfreeChart Mouseover or Mouse Click envent -

-

i want know how can know values of curve(dataset) when standing on over xyplot.

i've implement code kwnoing values of scale on axis:

    int mousex = event.gettrigger().getx();     int mousey = event.gettrigger().gety();      point mousepoint = new point(mousex, mousey);      // convert java2d coordinate axis coordinates...      chartrenderinginfo chartinfo = chart.getchartrenderinginfo();     point2d java2dpoint = chart.translatescreentojava2d(mousepoint);     plotrenderinginfo plotinfo = chartinfo.getplotinfo();      rectangle2d panelarea = chart.getscreendataarea(mousex, mousey);      double yy = math.round(plot.getrangeaxis().java2dtovalue(             mousepoint.gety(), panelarea, plot.getrangeaxisedge()));      stringbuffer stringb = new stringbuffer();     stringb.append("profundidad : " + yy);      // x coordinate same subplots     rectangle2d dataarea = plotinfo.getdataarea();      list<long> curvas = pista.getcurvas();      (int = 0, j = curvas.size(); < j; i++) {         if (curvas.get(i) != null) {             double puntoxx = plot.getdomainaxis(i)                     .java2dtovalue(java2dpoint.getx(), dataarea,                             plot.getdomainaxisedge(i));              double xx = (math.ceil((puntoxx + 0.05d) * 100)) / 100;              mdcurva curva = buscadoreslista.buscarenlistacurvas(curvas                     .get(i));             stringb.append(" " + curva.getnombrecurva() + " " + xx);         }     }      pbarraestado.getinstance().gettextosubestado2().settext(             stringb.tostring());

but, want know value of every curva in plot. can anywone me that

i'd start examples found under miscellaneous > crosshairs in jfreechart demo.
