dashboards are slow, but I
don’t have any way to
quantify it.

see the gray spinner

This is when you can
finally use the
dashboard

62. I took my laptop to a
meeting and went to show
the dashboard and it
refreshed right in my face!

64. Set a timer to pause the Viz before the timeout happens
Not pictured code
restarts this timer
every time the Viz is
interacted with
When you click to refresh, unpause and resume
Not pictured code
uses getFilterAsync()
and
getParameterAsync()
to restore your
previous state.

67. Instant
Dashboards

68. Your dashboard is too
slow!
I need it to load
INSTANTLY!

70. Dash Cache: Grab New Images
Trigger calls this once per refresh and stores it in a database as an
encoded string.

71. Dash Cache: UI Code to Display
Checks if there’s an image for
this dash. If so, decode it and
display it!
Tableau JS API to hide the Dash
Cache when the Viz is ready.
