New Post: how can oxyplot layer render and simple layout

oxyplot is perfect for the most 2d charting , but for more complex charting such as welllog logplot and geosection, which need layer render ,for example , plot background ,outline,gridline in layer, user dataseries(curve) is ether layer , if user data change, base layer don't rerender,it can improve chart perfmence. another problem how oxyplot layout , if oxyplot can't support layout ,it is not a complet charting system. i hope i can use oxyplot horizon layout or vertical layout . now oxyplot only an transform ,which user data(world data) transform to screen point (chart space), so it lack simple layout abilty
thanks
