Question

我想将xAxis的特定值反转。我希望我的栏看起来像这样：Goal Chart

我只想设置线条将变为正或负的行，我不在乎颜色。如果可能，请提供另一个图表库中的图表示例，或者给我一些有关如何创建Goal Chart

的提示

这是现场演示：

   var dom = document.getElementById("chart");
    var myChart = echarts.init(dom);
    var app = {};
    option = null;
    app.title = 'Bar Chart';
    
    var xAxisData = [];
    var data1 = [];
    var data2 = [];
    var data3 = [];
    var data4 = [];
    
    for (var i = 0; i < 30; i++) {
        if (i % 2 == 0){
            data1.push((Math.random() * 105).toFixed(2));    
        }
    }
    
    var itemStyle = {
        normal: {
        },
        emphasis: {
            barBorderWidth: 1,
            shadowBlur: 10,
            shadowOffsetX: 0,
            shadowOffsetY: 0,
            shadowColor: 'rgba(0,0,0,0.5)'
        }
    };
    
    option = {
        backgroundColor: '#eee',
       
        legend: {
            data: ['bar'],
