Setup

Setup in Tableau

Two short phases: add the Viz Extension to your workbook once, then drop the relevant fields on the new Marks Card.

Phase 1

Add the extension to Tableau

Open the Marks card and choose Add Extension On any Tableau worksheet (Desktop, Cloud or Server), open the Marks card dropdown and select "Add Extension". A new dialog will list available Viz Extensions.
Pick the Exchange listing or upload the .trex file Either choose "Access Extensions on the Exchange" for the free hosted build, or click "Access local extensions" and upload the .trex file you received with your LaDataViz license.
Review and accept the data-access prompt Tableau will ask you to allow the extension to read the worksheet's aggregated data. Accept it — a new Viz Extension Marks Card will appear next to Color, Size, Tooltip, etc.

Security & Privacy

Enterprise-grade by design

Every LaDataViz Viz Extension is built so your data never leaves Tableau. Here's exactly how we keep it that way.

No data is ever stored As a recognized Tableau Partner, your data is never stored anywhere — not even temporarily. Everything runs in your browser.

Only aggregated data The extension cannot access your data source’s raw fields. It only reads the aggregated marks the Worksheet already displays.

Cloud or on-premise Use the hosted cloud version, or deploy a packaged build inside your own environment with no internet connection required.
