when using x: { type: "time", ... } the a axis ticks are using correct local timezone, but the tip: "x" is still showing with utc timezones,

Plot.plot({
  color: { legend:true },
  x: { type: "time", domain: [new Date(Date.UTC(2024,3,8,-8)), new Date] },
  marks: [
    Plot.rectY(
      dataArticlesList,
      Plot.binX({y:"count", fill:"count"}, {x:"created_at", interval: d3.timeHour, tip: "x"})),
    Plot.ruleY([0]),
  ],
  width,
})

You currently need to use the format option to change how the tip mark formats channel values. But yes, perhaps the tip mark could check whether the channel’s associated scale is in local time.
