echarts鼠標移上去顯示數據

折線圖為例，核心代碼

<script src="/assets/webmaster/js/jquery.min.js"></script>
<script src="/assets/webmaster/js/echarts.min.js"></script>
<script type="text/javascript">
    // 基於准備好的dom，初始化echarts實例
    var myChart = echarts.init(document.getElementById('latest_pv'));

    // 指定圖表的配置項和數據
    var option = {
        xAxis: {
            type: 'category',
            data: ['{$d1}', '{$d2}', '{$d3}', '{$d4}', '{$d5}', '{$d6}', '{$d7}']
        },
        yAxis: {
            type: 'value'
        },
        series: [{
            data: [{$uv1}, {$uv2}, {$uv3}, {$uv4}, {$uv5}, {$uv6}, {$uv7}],
            type: 'line'
        }],
        tooltip : {
            trigger: 'axis',
            axisPointer: {
                type: 'cross',
                label: {
                    backgroundColor: '#6a7985'
                }
            }
        }
        };

    // 使用剛指定的配置項和數據顯示圖表。
    myChart.setOption(option);
</script>
