当数据量较少的时候,dataZoom的缩略图右侧最后一个数据点总是下降归0,趋势和正常数据不一样,看了很多图表都是这个样子的,是否可以修复这个bug?

var timeData = [
    '2009/6/12 3:00', '2009/6/12 4:00', '2009/6/12 5:00', '2009/6/12 6:00', '2009/6/12 7:00', '2009/6/12 8:00'];

timeData = timeData.map(function (str) {
    return str.replace('2009/', '');
});

option = {
    title : {
        text: '雨量流量关系图',
        subtext: '数据来自西安兰特水电测控技术有限公司',
        x: 'center'
    },
    tooltip : {
        trigger: 'axis',
        formatter: function(params) {
            return params[0].name + '<br/>'
                + params[0].seriesName + ' : ' + params[0].value + ' (m^3/s)<br/>';
        },
        axisPointer: {
            animation: false
        }
    },
    legend: {
        data:['流量','降雨量'],
        x: 'left'
    },
    dataZoom: [
