This feature is simple and powerful.
First, select “show highlighter” from the context menu on a discrete field that’s included in the view, specifically one that affects the view level of detail*.
Then search for the data you’re interested in, either a specific mark or a group of marks. And just like that, you’ll see that it’s highlighted.
That’s it. Now you can quickly find and compare sub-categories, see data in context, and notice patterns quickly.
You may have already noticed that in this example, color would not have been a great choice for highlighting and comparing. There are too many sub-category values, which would result in too many colors.
The highlighter control has dual support for text search and dropdown selection. You can add more than one highlighter to a viz, too.
You can also do ad hoc comparisons with instant highlighting. Hover over items in the highlighter dropdown, and instant highlighting allows you to ask and answer questions at the speed of thought.
For added analytics or more information, we recommend using the highlighter together with reference lines and bands, mark labels on highlight, or both, as shown in the following example:
Like the other tools in the family, the highlighter works everywhere: worksheets, dashboards, and stories. We’re excited to see how you put it to use across multiple views and in narratives.
