Por favor, sugíveme un ejemplo para la funcionalidad de flujo de DotyCothArt utilizando Graphael

Question

Estoy tratando de crear un gráfico de puntos (tabla de burbujas) usando Graphael. Pero su documentación no es tan clara sobre cómo agregar efectos de curiosidad cuando el usuario flota en los puntos. ¿Podría alguien por favor sugerirme algunos ejemplos o dar algunos consejos de ayuda en el mismo? Gracias de antemano.

Answer 1

Gracias por su respuesta, Cancerboero. Aquí está mi solución de guión Java,

dotChart.hover(function(){//onmouseover
        dotChart.covers = r.set();                                
        dotChart.covers.push(r.tag(this.x, this.y, this.value , 0, 10).insertBefore(this));                
    }, function(){//onmouseout
        if(dotChart.covers!=null){
            dotChart.covers.remove();
        }
    });

Esto ha funcionado bien :)

Answer 2

Tienes que usar AdteltArt.hoverdot () para registrarte un "listador Hover Dot Hover". El siguiente es el código fuente del ejemplo. http://cancerbero.vacau.com/gwt/graphael4gwtgallery/?test=dot1 Eso hace lo que mencionas. ¡Es el código de Java, no JavaScript! Pero creo que puede ayudarlo a hacer una idea del código JavaScript:

    double[] xs = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23,
            0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23,
