How to Create a Countdown Timer
A step by step walkthrough for building a live countdown to any date in PlotSet, with styled digits, an optional milestone list and an embed code you can paste anywhere.
约 6 分钟A live clock ticking toward your date, ready to embed on a page, is what you will have. You choose the target, the units and the look, and can add a short list of milestones beneath it.
Expect about six minutes. The clock works from the date alone, so a spreadsheet is optional and only needed for milestones.
你需要的数据
Optional. One row per milestone with a label and a date, and an optional note. With no data, the clock still runs from the target date you set.
The first column is the milestone name, the second its date and the third an optional note.
ISO dates, such as 2027-01-01, are the safest. Rows whose date cannot be read are still listed, sorted last.
The target can come from the first, next or last milestone instead of the date you set by hand.
Milestones are shown as a stacked list, not placed to scale along a timeline.
操作步骤
PlotSet 中从空白模板到完成图表的具体点击路径。
- 01
Open the Countdown template
From the PlotSet dashboard, start a new project and choose Countdown from the Other category. It loads with a sample event and a short milestone list.
每份指南都从这里开始：先选分类，再选模板，不管你要做哪种图表，用的都是同一个网格。 - 02
Set the target date
In the Target tab enter the year, month, day, hour, minute and second. Choose whether the time is read in the viewer's local time, in UTC or at a fixed offset.
Countdown 的「Preview」标签页。所有样式设置都在红框标出的这个面板里，每个设置各自占一个标签页：外观、标题、脚注，以及这种图表类型特有的选项。 - 03
Choose the units
In the Units tab pick which of years, months, weeks, days, hours, minutes and seconds to show. Two or three units read best.
- 04
Add milestones, or clear them
Import a CSV or .xlsx file, paste rows from a spreadsheet, or connect a Google Sheet. If you do not want a milestone list, clear the sample rows.
这里的数据视图取自一个条形图项目。你可以上传 CSV、用「Magic Import」从图片里提取数字，或同步 Google Sheet，每种图表类型的面板都一样。 - 05
Check the column bindings
Confirm which column holds the milestone label, the date and the note. This is usually right automatically when the headers are clear.
绑定决定哪一列作标签、哪一列提供数值、哪一列决定颜色。「Auto Binding」（自动绑定）会根据表头推测，所以要核对一遍，别想当然。 - 06
Style the digits and tiles
The Numbers, Unit labels, Tiles, Layout and Separators tabs control fonts, colours, boxes, spacing and the arrangement of the clock.
- 07
Write the lead-in and the expiry
Add a sentence above or below the clock, and in the When time runs out tab choose whether it stops, counts up or shows a message.
- 08
Publish and embed
Publish for a live clock and copy the embed code from the Share dialog. Check the time zone once more before you share it.
点「Share」，完成的图表就会变成一个公开链接和一段嵌入代码。
从已加载示例数据的 Countdown 模板开始，再替换成你自己的数据。
打开模板发布、嵌入或导出
最后一段路对每种图表都一样：「Share」（分享）把图表变成一个在线的公开链接和一段嵌入代码，「Export」（导出）把它输出成静态文件。
Share：公开链接与嵌入代码
打开嵌入代码和公开链接的开关，图表就发布出去了。链接可以放心发给任何人；嵌入代码以 iframe 的形式放进任意页面，悬停提示和交互效果都会保留。之后修改了图表，点「Recreate」就能把改动同步到链接和嵌入代码两边。
Export：SVG、PNG 或 JPG
「Export」会按你需要的尺寸输出一份静态副本。SVG 放到多大都清晰，还能在设计工具里继续编辑；幻灯片和文档用 PNG 或 JPG 最稳妥。想让图片在高分屏上够锐利，关键就是那个倍数设置。
Countdown 的样式提示
Pin the time zone
For a global event, interpret the target as UTC or a fixed offset so every viewer counts to the same moment.
Show fewer units
Days, hours and minutes are usually enough. Fewer units means bigger digits.
Plan for the expiry
Decide in advance whether the clock should stop, count up or show a message when the date arrives.
Use a progress ring
An optional bar or ring shows how much of the wait has passed.
制作 Countdown 时的常见错误
The clock shows zeros
The target is in the past, so it has expired. Set a future date or change the expired behaviour.
Readers see different times
The target is being read in each viewer's local time. Switch to UTC or a fixed offset.
The milestone list is empty
Filter settings may hide past rows. Check the Milestones tab and the dates in your file.
The digits are clipped
A large custom digit size can overflow a small chart. Reduce it, or keep auto-fit on.

Countdown：常见问题
No. The clock runs from the date you set. A spreadsheet only adds the milestone list.
