Highlighting
The article is outdated, read updated article about highlight data in official documentation of Power BI.
By default whenever an element is selected the values
array in the dataView
object will be filtered to just the selected values. This will cause all other visuals on the page to display just the selected data.
supportsHighlight
If you set the supportsHighlight
property in your capabilities.json
to true
you will receive the full unfiltered values
array along with a highlights
array. The highlights
array will be the same length as the values array and any non-selected values will be set to null
. With this property enabled it is the visual’s responsiblity to highlight the appropriate data by comparing the values
array to the highlights
array.
In the example above you’ll notice that the one bar that is selected is the only value in the highlights array. It is also important to note there could be multiple selections and partial highlight (where the corresponding numeric value in the values and highlights arrays will be present but different)
