I am working in the ArcGIS online version of Operation Dashboard, i need to have a category selector to filter all my widgets. i configure it and in the preview it seems ok, but in the dashboard it shows "No Data".
as a work around y added a list widget to do the same, but i have the same problem , the preview seem ok , it shows the data, but when I exit the configuration window , a no data label shows up in the widget.
is there something im doing wrong?
