我试图在每个情节上绘制多个带有形状的子图。从下面的代码中,如果我显示一个图,我得到以下图:
正如您所看到的,每个子图上应绘制的所有4条线都被绘制在左上方子图中的原始位置。我有什么想法可以解决这个问题吗?
**编辑 - 使用“纸张”
如果我在边缘形状的声明中使用xref和yref的“纸张”,则形状不能正确缩放。也许我在错误的背景下使用“纸”?我在下面附上了一张图片
library(plotly)
library(igraph)
tree <- make_tree(127,2)
tree_layout <- layout_as_tree(tree)
tree_layout_df <- as.data.frame(tree_layout)
Xn <- tree_layout_df[,1]
Yn <- tree_layout_df[,2]
edge_shapes = list(
type="line",
line=list(color="#030303",width=5),
opacity=0.3,
x0 = 0, x1=0,
x1 = 5,y1 = 5
)
reg_tree_plot <- plot_ly() %>%
add_trace(x=~Xn[0:63], y=~Yn[0:63], type='scatter', width=700, height=500)
tree_layout <- layout(reg_tree_plot, shapes=edge_shapes)
x <- tree_layout
y <- tree_layout
z <- tree_layout
sub <- subplot(tree_layout,y,z,x,
nrows=2,
margin=0.05,
shareX=FALSE,
shareY=FALSE)
答案 0 :(得分:2)
我认为这显然是subplot
中的一个错误,可以得到补偿,但它很丑陋,需要维护。如果将其发布到plotly站点并查看布局中的数据,则可以看到此信息。请注意,适当的坐标系似乎是:
这里有几个问题:
x0
时指定了edge_shape
两次。无论如何,这里有一些代码可以做你想要的(但是有轴bug)。
library(plotly)
library(igraph)
tree <- make_tree(127,2)
tree_layout <- layout_as_tree(tree)
tree_layout_df <- as.data.frame(tree_layout)
Xn <- tree_layout_df[,1]
Yn <- tree_layout_df[,2]
get_edgeshape <- function(xref,yref,xfak=1,yfak=1){
edge_shapes = list(
type="rect",
line=list(color="#030303",width=5),
opacity=0.3,
x0 = 0*xfak, x1 = 5*xfak,
y0 = 0*yfak, y1 = 5*yfak,
xref=xref,
yref=yref
)
}
reg_tree_plot <- plot_ly() %>%
add_trace(x=~Xn[0:63], y=~Yn[0:63], type='scatter', width=700, height=500)
ycor1 <- 2
ycor2 <- 2*1.125
tree_layout <- layout(reg_tree_plot, shapes=get_edgeshape("x1","y1",yfak=ycor1))
x <- layout(reg_tree_plot, shapes=get_edgeshape("x2","y2",yfak=ycor2))
y <- layout(reg_tree_plot, shapes=get_edgeshape("x3","y3",yfak=ycor1))
z <- layout(reg_tree_plot, shapes=get_edgeshape("x4","y4",yfak=ycor2))
sub <- subplot(tree_layout,y,z,x,
nrows=2,
margin=0.05,
shareX=F,
shareY=F)
sub
结果如下:
请注意,这不是一个很好的解决方案,如果您更改布局中的任何内容,则需要调整参数。只有一个情节修复才能真正解决痛苦。所以我在github网站上将其作为一个问题提交。

至少目前,如果您使用纸张坐标,则只会在subplot()
中重新缩放/重新定位形状和注释,例如:
rect <- list(
type = "rect",
xref = "paper", yref = "paper",
x0 = 0.5, x1 = 0.6,
y0 = 0.5, y1 = 0.6
)
p1 <- layout(plot_ly(), shapes = rect)
subplot(p1, p1)
