Java实现图表趋势图的展现

JS：

//评分趋势
progressLoadNew({
body: '#lineScore'
});
$.post(basePath + 'pfmReport/getExportReportKpiChartScoreData', {
dbid: dbid,
owner: owner,
table_name: tableName,
checkrecorderId: flcheckrecordid,
startTime: $('#beginTime').datetimebox('getValue'),
endTime: $('#endTime').datetimebox('getValue')
}, function(data) {
data = typeof data == 'string' ? JSON.parse(data) : data;

var obj, series = [];
series.push({
name: '评分趋势',
type: 'line',
data:data.data
});
obj = initBrokenLine('lineScoreView', data.dateList, [''], series, data.X_axis, data.Y_axis);
        setTimeout(function() {
report.score = obj.getDataURL();
        }, 1000);
progressCloseNew({
body: '#lineScore'
});
});
}

// 初始化折线图
function initBrokenLine(id, dateList, name, series, X_axis, Y_axis) {
    var options = {
        tooltip: {
            trigger: 'axis'
        },
        legend: {
            data: name,
        },
        xAxis: [{
            type: 'category',
            boundaryGap: false,
            data: dateList,
            name:X_axis,
        }],
        yAxis: [{
            type: 'value',
            name:Y_axis,
        }],
        grid: {
            x: 100,
            x2: 100,
        },
        series: series
    };
    var eChartColumn = echarts.init(document.getElementById(id));
    eChartColumn.setOption(options, true);
    return eChartColumn;
}
