When adding any dimension (or measure in case of a distribution cart) the step width is automatically determined. For some charts there are some options to influence this (e.g show top 10)
A helpful functionality would be to allow a user to determine custom/user defined steps.
For example in a distribution chart i could create 3 buckets based on case duration (<4 hours, 4-24 hours, >24 hours). Or in a standard column chart i could use a common dimension such as "Country" to create custom steps such as "Benelux", or "Dach".
Change step width of component, e.g. distribution chart
