I use the Cloudera Search (I use Hue 4)
and I am connected to a solr collection that contains these fields:
id (type string) ;
name (type string);
surname (type string)
latitude (type double)
longitude (type double)
in the collection I have 100 documents .
If I use, in a dashboard, the "marker map": it works well :
it asks me the field for latitude, and the field for latitude,
then I choose a label field (for example I choose "surname"):
and all work well (I see, in the world map, the markers in different positions) .
How Can I work also with the "gradient map"? :
if I insert, in a row of a dashboard, the "gradient map", then it asks me (in the upper zone of screen)
a field name for the filter: but if I choose (for example) "name" (or "latitude" or "longitude"),
I do not see something in the gradient map: I see nothing (only the world map, but no colours
in the nations): how can I use the gradient map? (I did not find detailed documentation
about the usage when a user is connected to a solr collection).
