Hi,
I'm using chartkick
and group_date
for a multiple series chart like the one in the readme, let's say:
<%= line_chart @users.map{|user| {:name => user.name, :data => user.orders.group_by_week(:created_at).average(:price)}
} %>
Is there a way to customize the tooltip via chartkick? (In the above example, I need to change date
format and round price
to the second decimal)
TIA
