Vegalite 中小十进制值的 y 轴刻度刻度
问题描述 投票：0回答：1
我正在尝试在 vegaLite 中创建一个具有双轴的图表。问题是，第二个 y 轴值是十进制的，如果我不使用第二个 y 轴的格式，那么它只是使用 4 位十进制数字进行格式。但我需要在点后最多 3 位小数。
如果我使用 format ("format":"0.3f") 那么它看起来像 y 轴上的重复值
我需要的所需视图仅在点后包含 3 个小数值并且不重复。
我根据动态数据值（字段最大值的 10% 额外。它是动态预先计算的）设置 maxDomain 第二个 y 轴值，而不使用 value:[] 。 怎么办？？

您的domainMax不够大。当您的domainMax仅达到0.0011时，为什么您的域会显示0.002？
尝试添加tickCount并增加您的domainMax：
