* 可配图形属性:
{
// 基础属性
shape : 'icon', // 必须,shape类标识,需要显式指定
id : {string}, // 必须,图形唯一标识,可通过'zrender/tool/guid'方法生成
zlevel : {number}, // 默认为0,z层level,决定绘画在哪层canvas中
invisible : {boolean}, // 默认为false,是否可见
// 样式属性,默认状态样式样式属性
style : {
x : {number}, // 必须,左上角横坐标
y : {number}, // 必须,左上角纵坐标
width : {number}, // 必须,宽度
height : {number}, // 必须,高度
iconType : {string}, // 必须,icon类型
},
// 样式属性,高亮样式属性,当不存在highlightStyle时使用基于默认样式扩展显示
highlightStyle : {
// 同style
}
// 交互属性,详见shape.Base
