Steps to reproduce

复制并替换成下面的代码，然后悬停在某个symbol上：

var hours = [];

var date = new Date();
var time = date.getTime();

for (var n = 0; n < 100; n++ ) {
    // hours.push(time   1000 * 60 * 60 * n);
    hours.push(n+1)
}

var days = ['Saturday', 'Friday', 'Thursday',
    'Wednesday'];

var data = [];

for (var i = 0; i < 4; i++) {
    for (var j = 0; j < hours.length; j++ ) {
        data.push([j, i, Math.random() * 10])
    }
}

option = {
    tooltip: {
        formatter: function (params) {
            return params.value[2];
        }
    },
    xAxis: {
        type: 'category',
        data: hours,
        boundaryGap: false,
        axisLine: {
            show: true
        }
    },
    yAxis: {
        type: 'category',
        data: days,
        axisLine: {
            show: true
        }
    },
    series: [{
        name: 'Punch Card',
        type: 'scatter',
        symbol: 'rect',
        symbolSize: function (val) {
            return [1, 20];
        },
        data: data,
        animationDelay: function (idx) {
            return idx * 5;
        }
    }]
};

What is expected?

能自定义symbolSize

What is actually happening?

symbolSize在hover时的放大比例不受控

---

散点图自定义了symbol:rect， symbolSize: [1, 20]
导致hover的时候放大比例异常，目前通过设置hoverAnimation: false和itemStyle.emphasis来简单的实现hover变化，有其他更好的解决方法吗？

目前暂不支持，可以考虑支持一下。

抱歉，我说错了，这个功能已经支持了，请使用 hoverOffset。
@susiwen8 对不起了……

@Ovilia ，这个hoverOffset好像只有pie图标才能支持配置

哦没看清楚是散点图……
