Highsoft released the new major version 6 for Highcharts, Highstock and Highmaps. There have been some great new chart types and features, and we adapted all our chart templates to use these new scrips.
We offer indeed some premium templates with builtin chart product themes, and no other styling. Question arises: why pay for these themes, as long as they are already offered for free by some other company?
Tooltips are one of the best interactive features to avoid clutter. Walk your mouse over an element to get instant information in a popup for that element alone. With no need to show that info permanently, for most visible elements.
