I have a anguler project and i want to use drilldown in my project. I'm using rest API to load data.
here what i notice is all the data is loaded when chart get load.
is there a way to load the data which is relevant when drilling down.
say we have 3 countries and cities. first we show countries. so we need to load country data.
when user click on one country say USA we need to fetch the data for usa cities, not all the cities .
Currently when the charts is loading it loads all the countries and cities
