Tooltip for Vega & Vega-Lite

A tooltip plugin for Vega and Vega-Lite visualizations. This plugin implements a custom tooltip handler for Vega that uses custom HTML tooltips instead of the HTML title attribute. Vega Tooltip is installed in the Vega Editor.

Installing

We recommend using Vega-Embed, which already comes with this tooltip plugin.

NPM or Yarn

Use npm install vega-tooltip or yarn add vega-tooltip.

Using Vega-tooltip with a CDN

You can import vega-tooltip directly from jsDelivr. Replace [VERSION] with the version that you want to use.

<!-- Import Vega 5 & Vega-Lite 4 (does not have to be from CDN) -->
<script src="https://cdn.jsdelivr.net/npm/vega@5"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-lite@4"></script>

<script src="https://cdn.jsdelivr.net/npm/vega-tooltip@[VERSION]"></script>

Usage and APIs

If you use Vega-Embed, you don't need to install Vega Tooltip! Vega Embed already comes with Vega Tooltip. You can however pass tooltip customizations.

vegaEmbed("#vis", spec, {tooltip: {theme: 'dark'}})
  .then(function(result) {
    // result.view contains the Vega view
  })
  .catch(console.error);

If you want to use a different version of the tooltip handler, you can override the default handler with the handler from Vega Tooltip (and you need to install it separately).

var handler = new vegaTooltip.Handler();
vegaEmbed("#vis", spec, {tooltip: handler.call})
  .then(function(result) {
    // result.view contains the Vega view
  })
  .catch(console.error);

See the API documentation for details.
