I have a question about using customized marker symbols with Vaadin Charts.
The method com.vaadin.addon.charts.model.Marker.setSymbol currently takes an object implementing the MarkerSymbol interface as a parameter. Possible classes implementing MarkerSymbol are MarkerSymbolEnum (giving you a choice of 5 pre-defined symbols) and MarkerSymbolUrl (giving you the chance to pass an url with the given image). For example, see https://demo.vaadin.com/charts/#SplineWithSymbols
Is there a simple way to attach text/Labels, Resources or FontAwesome symbols to Markers? The MarkerSymbol interface doesn't have any methods to implement, so I found no way to accomplish this that way.
