This example showcases a refreshing line chart application, where some amount of previous samples are left visible for a brief moment.
Older samples are constantly updated with increasing transparency colors to give a "decaying" effect.
This effect is achieved by preparing an individual
LineSeries for each displayed sample and updating the stroke style on every update.
Updating stroke style is a really fast operation, and there isn't any particular limit to the number of series either, so the amount of data in this kind of application can be scaled quite far up.
