可以使用`plot_ly()`函数和`add_trace()`函数来绘制带箭头的坐标轴的3D图。具体步骤如下:
1. 创建3D图表对象,并设置坐标轴的范围和标题。
```R
library(plotly)
# 创建3D图表对象
p <- plot_ly(x = c(-2, 2), y = c(-2, 2), z = c(-2, 2), type = "scatter3d",
mode = "markers", marker = list(size = 1))
# 设置坐标轴的范围和标题
p <- layout(p, scene = list(xaxis = list(range = c(-2, 2), title = "X"),
yaxis = list(range = c(-2, 2), title = "Y"),
zaxis = list(range = c(-2, 2), title = "Z")))
```
2. 添加箭头的起点和终点的坐标。
```R
# 添加箭头的起点和终点的坐标
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 1), y = c(0, 0), z = c(0, 0),
line = list(color = "red", width = 3))
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0), y = c(0, 1), z = c(0, 0),
line = list(color = "green", width = 3))
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0), y = c(0, 0), z = c(0, 1),
line = list(color = "blue", width = 3))
```
3. 添加箭头。
```R
# 添加箭头
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(1, 0.8), y = c(0, 0.2), z = c(0, 0),
line = list(color = "red", width = 3),
hoverinfo = "none", showlegend = FALSE)
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0), y = c(1, 0.8), z = c(0, 0.2),
line = list(color = "green", width = 3),
hoverinfo = "none", showlegend = FALSE)
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0.2), y = c(0, 0), z = c(1, 0.8),
line = list(color = "blue", width = 3),
hoverinfo = "none", showlegend = FALSE)
```
完整代码如下:
```R
library(plotly)
# 创建3D图表对象
p <- plot_ly(x = c(-2, 2), y = c(-2, 2), z = c(-2, 2), type = "scatter3d",
mode = "markers", marker = list(size = 1))
# 设置坐标轴的范围和标题
p <- layout(p, scene = list(xaxis = list(range = c(-2, 2), title = "X"),
yaxis = list(range = c(-2, 2), title = "Y"),
zaxis = list(range = c(-2, 2), title = "Z")))
# 添加箭头的起点和终点的坐标
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 1), y = c(0, 0), z = c(0, 0),
line = list(color = "red", width = 3))
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0), y = c(0, 1), z = c(0, 0),
line = list(color = "green", width = 3))
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0), y = c(0, 0), z = c(0, 1),
line = list(color = "blue", width = 3))
# 添加箭头
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(1, 0.8), y = c(0, 0.2), z = c(0, 0),
line = list(color = "red", width = 3),
hoverinfo = "none", showlegend = FALSE)
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0), y = c(1, 0.8), z = c(0, 0.2),
line = list(color = "green", width = 3),
hoverinfo = "none", showlegend = FALSE)
p <- add_trace(p, type = "scatter3d", mode = "lines",
x = c(0, 0.2), y = c(0, 0), z = c(1, 0.8),
line = list(color = "blue", width = 3),
hoverinfo = "none", showlegend = FALSE)
# 显示图表
