For the discrete chart I am unable to sort the data rows alphabetically so it is hard to find the row you need especially where names are similar.
Release : 21.3
Component : CA DOI AO PLATFORM COMPONENTS
there is no sort option for the Discrete visualization. If the data is static (i.e. the list if metrics returned doesn't change) then you could make use of the Organize Fields option in the transformation tab and define the order there - but if this list is dynamic i.e changes then this would not really help.
Request raised for this to be added to the product
