I recently decided to add visualisations for one of my projects and found that there's too many data points to visualise them and not all of them matter. Since there's a lot of various data being visualised (as a pie chart, with an option to switch to a different chart), I decided that it might make sense to add "other" as an option. Now there's the question - how should I define a threshold at which "other" appears? Should it be more like a sum of all items below a specific percentage, should I be looking at the number of data points or would a combination of the two be most effective?
Example data might look like this:
Item | Number of entries ------------------------- Ex. 1 | 100 Ex. 2 | 50 Ex. 3 | 10 ... | ... Ex.N-4| 1 Ex.N-3| 1 Ex.N-2| 1 Ex.N-1| 1 Ex. N | 1
In the context of the viewer, it's generally OK to sacrifice the
Ex. N entries if necessary by grouping them together in order to highlight the main entries.
