ZoomCharts Documentation

This is an optional field that may contain one or multiple columns of numerical values or text to be displayed in the tooltip when the user hovers or right-clicks a data point marker. This way, you can provide additional data to the user without cluttering the visual. 

You can also enter URLs in this field, and they will be clickable when displayed in the tooltip. Any strings beginning with 'https://' will be recognized as URLs, and the 'https://' part will be hidden in the tooltip. If the URLs are too long to be displayed in the tooltip, you can use the Hyperlink Length setting in the Tooltip Settings section to limit the maximum amount of displayed characters in URLs.
