How to use the Play button in browser in Tableau 2020.1
I dusted off a crazy 2014 Volvo Ocean Race workbook to show how the new play button finally works right in the browser.
- Tableau 2020.1 brought the parameter play button to the online/server browser experience, not just desktop.
- The browser play button runs slower than desktop, so design your visualisation with larger, less frequent time intervals to make the animation read well.
- Enabling animations can hide certain mark behaviours, such as the mark history effect used to trail the boats through the water.
- Combining animations with the play button on Tableau Server leads to slow performance, so use them with care.
- Refreshing an old workbook can be as simple as switching to a newer map style, adding map context, and adjusting font sizes to fit.
Tableau 2020.1 brought the parameter play button to the browser (Online/Server), not just Desktop, so animated parameter-driven visualisations now work for viewers who never open Desktop. Tim revisits an old workbook to show how it behaves once published and where it falls down.
Tim dusts off a 2014 workbook built for a Volvo Ocean Race challenge, where a parameter slider with a play button steps through boats' logged positions over time. He refreshes it before republishing to Tableau Online to test the new browser play button.
- Old workbook, dated map and fonts 0:00
Tim opens a workbook last saved in Tableau 8.3 that uses a parameter slider with a play button to animate marks changing state over time — the same mechanism this video is about testing in-browser.
- Refresh the map style and add context 1:17
As a quick tip when reviving old vizzes, swap outdated map styles for a current one and add map context layers before worrying about anything else — it's a fast visual win.
- Resize fonts to fit the layout 1:43
Another independent tidy-up: if text overruns a dashboard, drop the font size (he uses 14) and reapply — simple but necessary before republishing so nothing looks broken to viewers.
- Confirm the play button works on Desktop first 2:01
Before publishing, check the parameter's play button animates correctly on Desktop (speed set to fast, stepping through each recorded state) so you know the baseline behaviour you're comparing the browser against.
- Publish to Tableau Online 2:42
Publish the workbook as normal, choosing which sheets/tabs to show; this step must happen before you can test the browser-specific play button behaviour that 2020.1 introduces.
- Play button runs slower in-browser 3:28
On Tableau Online the play button works, but it plays more slowly than on Desktop because it relies on browser rendering rather than Desktop's engine. Design around this: use larger, less frequent time intervals so each animated step reads clearly at the slower browser pace.
- Animations can hide certain mark effects 4:37
Turning on the separate animations setting changes how the play button behaves — in Tim's case it made a 'mark history' trail effect (used to show boats moving through water) disappear entirely. Test your dashboard with animations both on and off to check nothing you rely on gets suppressed.
- Animations plus play button hurts performance 5:40
Animations look good on Desktop, partly controlled by the duration setting, but combining animations with the play button on Tableau Server leads to slow performance — use the pairing carefully, or avoid it if performance matters more than the effect.
- The browser play button is noticeably slower than the Desktop version, so demo pacing on Desktop won't match what viewers see online.
- Enabling animations can hide mark behaviours like history/trail effects, so check your visualisation carefully with animations toggled on.
- Animations combined with the play button on Tableau Server specifically causes slow performance — a combination worth avoiding or testing thoroughly first.
Reach for this when you're publishing a parameter-driven animated dashboard to Tableau Online or Server and need viewers (not just Desktop users) to be able to hit play — but test speed and animation interactions first rather than assuming Desktop behaviour carries over.
How this Rollup was made provenance & method
A Rollup is drafted by AI from the video's transcript, then reviewed and edited by Tim. Everything used to produce this one is listed below — the model, the exact prompt, and the source video — so the process is transparent and reproducible.
- Transcription
- On-device — NVIDIA Parakeet v3 for recent videos, OpenAI Whisper large-v3 for earlier ones. The transcript never leaves the machine or gets published.
