AnyStock tooltips support full HTML formatting with custom CSS, enabling branded, card-style hover popups that go far beyond plain text. This is especially useful in multi-plot layouts where each series contributes different data fields.
This sample renders AAPL candlesticks with a volume column overlay on the first plot and a KDJ indicator on the second. The tooltip uses HTML title and union formatters with custom CSS to display an Apple logo, OHLC values, volume, and KDJ readings in a styled table card. A line scroller and range controls complete the layout.
