Sample Description
How to use this sample?
Use option selector to the right of the chart to switch data grouping intervals.
How it works
AnyChart Stock gives you the ability to use Data Grouping, which is very useful for showing large data sets, you can read about this in Data Grouping and Values Approximation article.
In this sample we use the ability to change chart properties on-the-fly via objectModel (more in Updating Chart using Object Model article) to change data grouping interval unit.
