Is it possible to have a different marker style for ranges among (XY-Axis) values ? For example. The marker style is shown in steel blue color here, Can I have markers above 15 and below 13 to show another color ?Display:
With a TwoColorLineSeries should be possible to have 2 zones. If what you need are 3 zones ( x<13; 13<x<15; 15<x ) maybe you should check ScatterSeries...
