Version

v2.15.0

Development Environment

Chrome, OSX

Current Behavior

Series is rendered in order to series index.
priority of 크리스마스, the 0 index is higher than 달력, the 1 index.

As two series has same data 0, we could only show tooltip of 크리스마스.
However, when 달력 is selected inside legend area. It should show tooltip of 달력.
Because selection means 달력 series will only be activated.

var container = document.getElementById('chart-area');
var data = {
       categories: ['2018.01.25'],
    series: [
          {
            name: '크리스마스',
            data: [0]
        },
        {
            name: '달력',
            data: [0]
        }
    ]
};
var options = {
    chart: {
        width: 400,
        height: 300,
        title: '날짜별 검색량'
    },
    series: {
        showDot: true
    }
};
var chart = tui.chart.lineChart(container, data, options);

Expected Behavior

When 달력 is selected inside legend area. It should show tooltip of 달력.
