I saw a chart the other day that had a cool miniature image of itself inside of the scroller. I would love to know how to do something similar. The chart I am refereeing to can be found here: Daily Nav
You can do that using background series option of the scroller, as described at https://docs.anychart.com/7.14.3/Stock_Charts/Scroller#background_series
Basic sample is available at https://playground.anychart.com/docs/7.14.3/samples/STOCK_Scroller_03-plain
Any of the series available for stock charts https://api.anychart.com/7.14.3/anychart.enums.StockSeriesType can be displayed in the scroller.
