Encoding icon tokens for viz extensions

The complete list of encoding-icon tokens a Tableau viz extension can use on a Marks-card tile, which ones are proven, and why line and detail are rejected.

Eric SummersUpdated 2026-09-18markdown

Every Marks-card tile in a viz extension needs an <encoding-icon>. Tableau accepts exactly 78 tokens, and every tile on the same extension must use a distinct one, or Tableau throws ED626076 and refuses to add the extension.

The public docs are wrong here. Tableau's published list includes line and detail, but the compiled schema rejects both. This table is transcribed from the schema, so it matches what actually loads.

Verified vs unproven

The Verified column marks tokens the team has seen render on a tile in Desktop. A token that is valid-but-unproven is schema-legal but may not draw, so the check engine warns rather than blocks.

FAQ

What does ED626076 mean?

Two Marks-card tiles use the same encoding icon. Give each tile a distinct token from this list.

Can I use the "line" or "detail" icon?

No. The public docs list them but the schema rejects both. Pick another token.
