This example shows usage of different Markers of the ChartXY environment.
Markers are custom UI-elements that can be used to draw custom cursors from user side. There are two types of Markers:
This type of Marker is placed along two arbitrary axes belonging to a ChartXY. It is positioned with axis values, and will look exactly like an AutoCursor. It also has the same capabilities as one - only difference being that it isn't automatically positioned and hidden when needed, users have full power over this logic.
SeriesMarkers are a part of certain series (line-series, OHLC, …?), that can be created using series-method: addMarker. Once again, the SeriesMarker doesn't look any different from other Markers, the only logic which it adds is that it automatically latches to the nearest data-point of its owning series, from its current location (which can be set using method: setPosition)
