我正在试验这段代码,我试图在情节上方获得网格线。
使用的代码与 OP 中的相同:
#Orignal Data as per Question
a <- c(0.1, 0.5,0.5, 0.6, 0.2, 0 , 0 , 0.004166667, 0.45)
b <- c(0.75,0.5,0 , 0.1, 0.2, 0.951612903,0.918103448, 0.7875 , 0.45)
c <- c(0.15,0 ,0.5, 0.3, 0.6, 0.048387097,0.081896552, 0.208333333, 0.10)
d <- c(500,2324.90,2551.44,1244.50, 551.22,-644.20,-377.17,-100, 2493.04)
df <- data.frame(a, b, c, d)
#For labelling each point.
df$id <- 1:nrow(df)
#Build Plot
ggtern(data=df,aes(x=c,y=a,z=b),aes(x,y,z)) +
stat_density2d(geom="polygon",
n=400,
aes(fill=..level..,
weight=d,
alpha=abs(..level..)),
binwidth=100) +
geom_density2d(aes(weight=d,color=..level..),
n=400,
binwidth=100) +
geom_point(aes(fill=d),color="black",size=5,shape=21) +
geom_text(aes(label=id),size=3) +
scale_fill_gradient(low="yellow",high="red") +
scale_color_gradient(low="yellow",high="red") +
theme_tern_rgbw() +
theme(legend.justification=c(0,1), legend.position=c(0,1)) +
guides(fill = guide_colorbar(order=1),
alpha= guide_legend(order=2),
color="none") +
labs( title= "Ternary Plot and Filled Contour",
fill = "Value, V",alpha="|V - 0|")
#Save Plot
ggsave("TernFilled.png")
是否可以在轮廓上方获得网格线?
更新
为了获得顶部的网格线,我更新到 ggtern 2.1.0。更新后,我必须更改 stat_density2d -> stat-density_tern 和 geom_density2d -> geom_density_tern 几个更改才能使代码正常工作。尽管它编译了下图,但我无法重现上图。而且我必须添加 na.rm = TRUE 才能使代码正常工作
library(ggtern)
#Orignal Data as per Question
a <- c(0.1, 0.5,0.5, 0.6, 0.2, 0 , 0 , 0.004166667, 0.45)

d <- c(500,2324.90,2551.44,1244.50, 551.22,-644.20,-377.17,-100, 2493.04)

stat_density_tern(geom="polygon",

aes(fill=..level..,
weight=d,
alpha=abs(..level..)),
na.rm = TRUE) +
geom_density_tern(aes(weight=d,color=..level..),
n=400,
na.rm = TRUE) +
geom_point(aes(fill=d),color="black",size=5,shape=21) +
geom_text(aes(label=id),size=3) +

scale_color_gradient(low="yellow",high="red") +
# theme_tern_rgbw() +

guides(fill = guide_colorbar(order=1),

为什么我不能用以前的 ggtern 版本和更新的版本获得地块?binwidth 用什么代替?
