Axes Marker
There are three types of markers on the axes, these are Line Markers, Range Markers, and Text Markers. Line Markers are lines that are drawn on the chart and bound to some values on the axis. They can be used to show trends or mark important values. Range Markers are colored areas bound to a chart axis. These areas are useful when one needs to highlight some values on the axis. Text Markers are useful when one wants to place custom texts or description with axes values labels or instead of them. They can be added to any place of a chart.
