apexcharts.js 始终显示一定数量的水平线

Question

我用 2 个不同的数据集创建了相同的 apexchart。图 1 的水平线看起来很棒。但是图表 2 只有 1 条水平线。

图表 1 和图表 2 之间的唯一区别是数据集。如何始终在图表上显示 5 条水平线？

Answer 1

它在两个图表上都显示，只是在第二个图表上只显示一个。这是因为 y 轴的刻度数是根据数据自动计算的，但是您可以使用 tickAmount:

来设置它

yaxis: {
  tickAmount: 5
}

let InfoinfoDisplay_color = "rgba(1, 100, 148, 0.95)";
let InfoHovercolor = "rgba(1, 100, 148, 0.95)";
