Ignore certain traces in autoscaling

Feature request to ignore certain traces when doing autoscaling.

My use case is that I have a few scatter plots with colored shapes in the background indicating categories of the data. The category shapes are implemented as traces and are hidden from legend. If I mute some of the scatter plots, it would be ideal if scale adjusts to the data that remain. As it is, autoscale will be constant, just adjusted to the background shapes.

首先，使用背景类别 traces 和静音的散点图 traces 重现 autoscaling 行为，并以 issue 的散点图场景作为切入点。当 autoscale 忽略选中的 traces、同时仍包含其余数据，并且该行为由适当的测试覆盖时，修改即告完成。
