You have to use scale_shape_identity -- that tells it to use the numeric codes directly for point shapes: ggplot(data=data.frame(x=c(1:16))) + geom_point(aes(x=x,y=x,shape=x)) + scale_shape_identity() WinVector closed this as completed Apr 26, 2012 Author WinVector commented...

我想让第一个 geom_point(data = may_sonde_ph_situ) 在点周围有一个黑色轮廓,以便它们在图中突出。使用该 geom_point 仅绘制了 12 个数据点。 我还希望这些 geom_point 形状的图例具有与图形上显示的颜色适当的颜色。现在,它们的形状和颜色编码为它们的视线名称,并且它根据其他 geom_point 调用的视线匹配...
* create various shapes (points, circles, lines, ellipses, polylines, polygons) using an intuitive syntax. Ex: createCircle(p1, p2, p3) to create a circle through 3 points, create parallel and perpendicular lines * compute intersections between 2 lines, between a line and a circle * work...
在ggplot函数系统中，形状是一类重要的映射属性，如同颜色一样，它可以被赋予给变量，当然也可以直接指定...
Abstraction leads from the concept of extension of bodies to the concepts of surface, line, and point. This is clearly expressed, for example, in the definitions given by Euclid:“a line is a length without breadth” and “a surface is that which has only length and breadth.” A point ...
If given, only every (n+1)th child shape or point is being processed and the others ignored. Useful for low detail test runs. sort: Ordering function (in lieu of full path planning/optimization, which is planned for a later stage). For shapes other than points(), order of appearance ...
抖动(Jitter)是一种在数据可视化中用于解决重叠点或线条问题的技术。在ggplot2中,抖动可以通过geom_line和geom_point函数来实现。 抖动geom_line函数用于绘制抖动线...
