Unanswered: interaction and performance
just wondering what it the limplication of adding numorous interactions on the chart assuming my app is focused on iphone/android devices.
also, what about smaller additions like using markers, animation, line chart fill, smoothing etc.. do they have impact on performance?
The number of interactions doesn't have any noticeable impact, but you have to be careful about usability if you thow too many on a single chart.
The other additions you mention all impact performance. Opacity and line fills have some of the largest impact that we've seen.
