在数据可视化领域，ECharts 是一款非常流行的 JavaScript 库，它可以帮助我们轻松创建各种图表。而图标样式，作为图表的重要组成部分，往往能直接影响到图表的整体视觉效果。今天，就让我来带你一起探索如何自定义 ECharts 图标样式，让你的图表更加炫酷！
1. 了解 ECharts 图标样式
在 ECharts 中，图标样式主要分为以下几类：
- 标记点（Symbol）：图表中的数据点所使用的图标。
- 边框（Border）：图表元素周围的边框样式。
- 阴影（Shadow）：图表元素周围的阴影效果。
- 文本（Text）：图表中的文本样式。
2. 自定义标记点（Symbol）
标记点是图表中最常见的元素，自定义标记点可以让你的图表更具个性。以下是一个简单的例子：
”`javascript var myChart = echarts.init(document.getElementById(‘main’));
var option = {
series: [{
type: 'scatter',
data: [[10.0, 8.04], [8.07, 6.95], [13.0, 7.58], [9.14, 8.14], [6.26, 7.25], [7.67, 3.11], [4.94, 7.25], [12.74, 7.11], [9.26, 8.34], [5.92, 2.23], [8.47, 9.02], [11.34, 7.23], [4.76, 6.42], [7.71,
