Issue

Map is not automatically zoomed when opening a hyper file generated by Alteryx by Tableau Desktop 2018.1 and later.
In Tableau Desktop 10.5 and older, the map was automatically zoomed up when opening a hyper file including polygons generated by Alteryx.
User-added image
When opening the same hyper file by Tableau Desktop 2018.1 and later, the map is displayed as below.

Environment

Tableau Desktop 2018.1 and later
Alteryx

Resolution

Install Hyper API v0.0.11074 and later. The functions geo_auto_vertex_order and geo_invert_vertex_order is available to manipulate the vector order of polygons.
For more details about the functions, please see 2.14. Geographic Functions of the Hyper SQL documentation.

Cause

A hyper file generated by Alteryx uses a different winding order for polygons than the one used by Tableau. The functions geo_auto_vertex_order and geo_invert_vertex_order can be used to address the problem.
