The Data Canvas is a great place to manage, wrangle, cleanse, and enrich data. However, the options for formatting column data types are not found within it. You must leave the canvas and go to the Data Panel column handler then select the gear icon which is all somewhat un-intuitive.
Add an integrity data KPI in %. exemple if some cells have not the same format as the colon values
Add a % of empty values in addition to the number of empty values
I suppose my trouble here is primarily between navigating back & forth. If the existing Data Panel could simply be made visible/interactive while the Data Canvas was in view, it would mostly resolve this for me.
