How to Create a Marker Map
A step by step walkthrough for plotting places with emoji or image icons, labels, a legend and custom popups in PlotSet.
约 7 分钟You will end up with a map where each row of your data is a marker, with an icon for its category, a name beside it and a popup.
Expect about seven minutes. Most of it goes on choosing the icons and writing the popup.
你需要的数据
One row per place, with a latitude and a longitude and, if you want them, a name, a category and a number.
Latitude runs from -90 to 90 and longitude from -180 to 180, as plain numbers.
A category column gives each group its own icon and a legend.
A number column scales the markers so their area follows the value.
A row without usable coordinates is skipped and counted under the map.
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 Marker Map template
From the PlotSet dashboard, start a new project and choose Marker Map from the Maps category. It loads with fifty gem exports by country.
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 places
Import a CSV or .xlsx file, paste rows from a spreadsheet, or connect a Google Sheet. Each row becomes one marker.
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
Bind the latitude and longitude columns first. Then choose a label, a category and, if you want sized markers, a number column.
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
Pick an icon for each category
In the Markers tab, give each category an emoji or an image link, one per line, in the form name: icon.
Marker Map 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
Write the popup
In the Tooltip tab, write a header and body, and put column names in double braces to fill in each place's values.
- 06
Tune the labels and legend
The Labels tab sets the font and halo, and the Legend tab shows icons or colour swatches with your own title.
- 07
Set the view
The Basemap tab sets tilt, rotation and the projection. The Inset tab adds a small globe that shows where the view sits.
- 08
Publish and embed
Publish for a live chart and copy the embed code from the Share dialog. Check the map at the width of your page 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 Marker Map 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。
Marker Map 的样式提示
Use emoji for quick icons
An emoji looks the same on every device and needs no image hosting.
Keep categories few
Five or six icons stay easy to tell apart in the legend.
Link your source
A source line under the map tells readers where the figures came from.
Size by area
A size column scales the area of each marker, so twice the value looks twice as big.
制作 Marker Map 时的常见错误
Markers are in the wrong place
Latitude and longitude are probably swapped. Check that latitude is the first number.
Some names are missing
Labels that overlap are hidden. Zoom in or hover over a marker to see its name.
A popup shows the plain list
A name in double braces did not match a column. Check the spelling against your headers.
A warning appears under the map
Some rows had no usable coordinates. Fill them in or remove them.
