昨天一个好朋友扔过来这样一张图，让帮忙看看。虽然很忙，但是没做过图标的我很是好奇，就答应下来帮忙看下。看似一个简单的折线图，实则需求很复杂。仔细分析之后需求如下：
设计图
1.两条X轴，X1轴坐标显示，X2轴坐标隐藏
2.两个Y轴，Y轴都是从0开始，暂且称为Y1轴，Y2轴。Y1轴取值范围从0到8，以2间隔；Y2轴取值范围从0到5，以1为间隔
3.多条不同颜色的折线，折线点为实心圆
4.以X轴分段划分区域，设置不同背景色，区域中心设置文字，低风险、高风险
5.图标背景，以X轴方向的横条显示，底色为白色
6.右下角按钮 （不在画图范围内，暂时忽略）
7.X轴上按区域进行分段 蓝橙色提示😢
根据以上需求我开始选用ECharts画图，说到这里不得不提一句，ECharts真好用啊，强大的功能，清晰的API。我第一次使用就很容易，入门无门槛。😄
最终实现的效果如下：
