双折线共用坐标轴时，如果一个折线的字段无值，会导致所有折线都不能正常展示，而且坐标轴的排列变得很乱

满足两个条件： 1、图表中的两条折线共用一个坐标轴，即都没有设置independent: true 2、数据中其中一条折线的字段，不存在任何值（备注：只要有一个值页面展示都是正常的）
坐标轴的刻度最起码要展示正常
场景就是，我们需要展示环比上月和同比去年的数据，但是去年并没有数据，所以导致这个字段值无值，而且把值设置为0也是不合适的，因为去年没有数据
可以先暂时这样解决一下：
chart .line() .encode("x", "Month") .encode("y", "Temperature") .encode("color", "#EE6666") .encode("shape", "smooth") .scale("y", { type: 'linear' }) // 添加这一行 .axis("y", { title: "Temperature (°C)", grid: null, titleFill: "#EE6666", });
我进一步看看这是否是属于一个 bug。
