How to draw rectangle over a plot?

问题 Is it possible to draw rectangle using OxyPlot? Something like : or does OxyPlot not support this? 回答1: You can indeed. There's a couple of ways you can do it. I would prefer to use an annotation as this will also give you a highlighted background and give you the option to add click events on this area. There's probably a way to remove the highlight if you want to make it look like the image you've provided. var Event = new PolygonAnnotation(); Event.Layer = AnnotationLayer.BelowAxes; Event

问题 Im trying to change the format of the value next to the axis from for example 1000 to 1k or 1000000 to 1M. Is this possible in LinearAxis? This is my Code: m.Axes.Add(new LinearAxis { Position = AxisPosition.Right, IsZoomEnabled = false, IsPanEnabled = false, Minimum = -(_maxPointValue2*0.1), Maximum = _maxPointValue2 + (_maxPointValue2*0.1), FontSize = 15, Key = "right", TickStyle = TickStyle.Outside, }); Is this perhaps possible with StringFormat? Also is it possible to change the TickStyle
