但映射点的颜色时,应该用color而非fill。同样地,修改图例时也需要将上述方法的fill改成color(对应即可)。 如作图数据如下: 当用fill时: ggplot(data=NMDS, aes(MDS1,MDS2,fill=group))+geom_point() 用color: ggplot(data=NMDS, aes(MDS1,MDS2,color=group))+geom_point() 如果要将点同时映射颜色和形状...
ggplot(data = NMDS, aes(MDS1,MDS2,fill=group))+geom_point() 1. 用color: ggplot(data = NMDS, aes(MDS1,MDS2,color=group))+geom_point() 1. 如果要将点同时映射颜色和形状: p <- ggplot(data = NMDS, aes(MDS1,MDS2,color=group,shape=group)) +geom_point() 1. ...
ggplot(heightweight, aes(x = ageYear, y = heightIn)) + geom_point(shape = 1, size = 4, stroke = 2)如果想要使用特定的shape样式，可以直接在geom_point()函数中使用shape参数。例如，使用shape = 3创建一个特定的点形状。在aes映射中，可以将shape映射到分组变量，并通过scale_shape_man...
一般而言,我们修改ggplot2图例标题,常用以下三种方法: 但映射点的颜色时,应该用color而非fill。同样地,修改图例时也需要将上述方法的fill改成color(对应...

一、R中散点的shape的种类 对于1-20,不管是空心还是实心,通通用colour语句映射; 对于21-25,存在一个外边界(outline)和内里(the fill)的颜色。外边界的颜色由colour语句控制,而内里颜色由fill语句控制。 二、stroke参数调整点的路径的粗细 ggplot(heightweight, aes(x = ageYear, y = heightIn)) + ...
