How to Create a Draw the Line Chart
A step by step walkthrough for building a line chart that asks readers to draw the rest of the trend, then reveals the real line with a score, in PlotSet.
约 7 分钟A line chart that stops partway and lets the reader draw the rest is what you will have. When they submit, the real line is revealed and their guess is scored.
Expect about seven minutes. Most of it goes on choosing where the line stops and writing the feedback.
你需要的数据
A first column for the x axis, such as years, then one column per line. Some columns are guessed by the reader, and others can stay fixed as context.
The x column can be text, numbers or dates, with one row per point.
Each guessed column becomes a line the reader has to draw. Fixed columns are always drawn in full.
At least one row must remain after the drawing point, or the chart becomes a plain finished line chart.
All lines share one vertical axis, so keep them on a similar scale.
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 Draw the Line template
From the PlotSet dashboard, start a new project and choose Draw the Line Chart from the Line and Area category. It loads with a sample of US coal and wind and solar share.
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
Add your data
Import a CSV or .xlsx file, paste rows from a spreadsheet, or connect a Google Sheet. Put the x values in the first column and one line per column after it.
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。 - 03
Check the column bindings
Choose which columns the reader will guess and which stay fixed. The x axis column is the label.
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。 - 04
Set where drawing starts
In the Drawing tab choose what share of each line is shown before the reader takes over. Pick a point that leaves the next move uncertain.
Draw the Line Chart 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。 - 05
Choose how the reveal plays
In the same tab, pick whether the real line wipes, fades or draws itself in, and whether guesses snap to steps.
- 06
Write the prompt and the feedback
The Prompt and Score messages tabs hold the instruction, the submit button text and four tiers of feedback, with a token for the size of the gap.
- 07
Style the lines and axes
Use the Color, Lines, X axis, Y axis and Legend tabs to set the look. The Y axis tab controls the baseline and headroom.
- 08
Publish and embed
Publish for a live chart and copy the embed code from the Share dialog. Play it through yourself once, including the reveal, 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 Draw the Line Chart 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。
Draw the Line Chart 的样式提示
Stop before the interesting part
Cut the visible line just before the turn, so the reader has a real decision to make.
Write feedback with a voice
Tailor the four score messages to your story rather than keeping the generic text.
Add a fixed context line
A second line that is always visible gives the reader something to reason from.
Keep keyboard mode on
It adds a slider per point, so readers without a mouse can still play.
制作 Draw the Line Chart 时的常见错误
There is nothing to draw
The drawing point is at or near the end of the data. Lower the share of the line that is shown.
One line is squashed flat
The lines are on very different scales and share one axis. Set a custom axis range or use similar units.
The tooltip does not show the hidden values
This is by design. Values on the hidden stretch only appear after the reveal, so hovering cannot leak the answer.
The PNG shows the wrong stage
A static export captures whatever stage the chart is in. Reveal the line before you export.

Draw the Line Chart：常见问题
Yes. Bind several columns as guessed lines, and the reader draws each in turn.
