在plotly中避免重复图例可以通过设置legend.group参数来实现。legend.group参数可用于指定相同组的图例将归为一组,并在图例中仅显示一次。具体步骤如下:
install.packages("plotly")
library(plotly)
x <- c(1, 2, 3)
y <- c(1, 4, 9)
z <- c(10, 5, 0)
p <- plot_ly() %>%
add_trace(x = x, y = y, name = "Trace 1", type = "scatter", mode = "markers",
marker = list(size = z, sizemode = "diameter")) %>%
add_trace(x = x, y = y, name = "Trace 2", type = "scatter", mode = "markers",
marker = list(size = z, sizemode = "diameter"))
p
p <- plot_ly() %>%
add_trace(x = x, y = y, name = "Trace 1", type = "scatter", mode = "markers",
marker = list(size = z, sizemode = "diameter"), legendgroup = "Group 1") %>%
add_trace(x = x, y = y, name = "Trace 2", type = "scatter", mode = "markers",
marker = list(size = z, sizemode = "diameter"), legendgroup = "Group 2")
p
在R中垂直设置标题可以使用layout函数中的title参数来实现。具体步骤如下:
p <- plot_ly(x = x, y = y, type = "scatter", mode = "markers")
layout <- list(title = "垂直标题示例",
xaxis = list(title = "X轴"),
yaxis = list(title = "Y轴"))
p <- layout(p, layout)
p
通过设置title参数,可以指定图形的垂直标题。如果需要设置x轴和y轴的标题,可以在layout函数中使用xaxis和yaxis参数来实现。
综上所述,以上就是如何在plotly中避免重复图例并在R中垂直设置标题的方法。对于更详细的plotly用法和其他功能,可以参考腾讯云产品的官方文档:plotly文档
