Box Plot

The spread of a value within each group – median, middle 50%, whiskers, mean and outliers – to compare groups fairly.

When to use it

Use it to compare spreads between groups, not just their averages – who's consistent and who's all over the place.

Questions it answers

How to use it

  1. On your dashboard page, add a grid with the columns below (or map your own header names – see below). Keep it on the same page – tuck it behind the chart rather than hiding it, and make it tall.
  2. Add an HTML container (one that runs JavaScript) and paste the snippet.
  3. View the page. The chart finds the grid, reads every row and draws itself; it updates when filters change the grid.
Default headerKeyWhat it's for
Dimension AdimARequiredThe group – needs at least 3 values each.
Metric 1v1RequiredOne value per grid row.
Snippet for the HTML container

The integrity value pins this exact version: the browser refuses to run the script if a single byte changes. New versions get a new file name and a new snippet, so a dashboard only changes when you paste the new snippet.

Your own column names

The chart looks for the default headers above. If your grid's headers are different, map them by key with data-columns on the placeholder – the chart then shows your names too. data-labels (same keys) changes just the on-screen names, and data-title changes the heading. For grids that draw rows in batches, data-grid-class and data-scroll-class name the grid's container and its scroll box so every row is read.

Example
<div data-chart-embed="box-plot" data-columns='{"month":"Your Month Header","v1":"Your Metric Header"}' data-title="Your title" style="height:100%"></div>
