如何在带有颜色变量的 R Plotly 条形图中保留所需的顺序
How can I retain desired order in R Plotly bar chart with color variable
不言而喻。如果调用颜色参数,则 x 轴上的值排序不正确
df <- structure(list(count = c(8, 3, 5, 9), names = c("I", "want",
"this", "order"), type = c("H", "A", "H", "A")), .Names = c("count",
"names", "type"), row.names = c(NA, -4L), class = "data.frame")
plot_ly(data=df,x=names,y=count,type="bar",
color = type)
这与 有点相似,但似乎有点难以在这里应用
TIA
更新:plotly_4.5.6 包含一些更改(水平线下方的原始答案)
我原来的答案可以修改为:
p <- plot_ly(data = df, x = ~names, y = ~count, type = "bar", color = ~type)
p <- layout(p, xaxis = list(categoryarray = ~names, categoryorder = "array"))
p

您可以利用对 plotly 所做的更改(阅读更多 here):
Also, the order of categories on a discrete axis, by default, is now
either alphabetical (for character strings) or matches the ordering of
factor levels.
# set the factor order however you want
df$names <- factor(df$names,
levels = c("I", "want", "this", "order"))
# plot it (note, plotly can now infer the trace, but I specified as "bar" anyway
plot_ly(data = df, x = ~names, y = ~count, color = ~type, type = "bar")
原答案
使用 layout
和您可以提供给 xaxis
的参数。具体来说,您要设置 categoryarray = name
和 categoryorder = "array"
。来自 https://plot.ly/r/reference/ 的布局部分:
Set categoryorder
to "array" to derive the ordering from the
attribute categoryarray
.
p <- plot_ly(data=df, x=names, y=count, type="bar", color = type)
p <- layout(p, xaxis = list(categoryarray = names, categoryorder = "array"))
p
