剧情地将源或标题添加到图表 [英] plotly adding a source or caption to a chart

问题描述

是否有一种方法可以将数据源/标题添加到Plotly中的图表，类似于在ggplot中使用caption参数可以完成的操作:

labs(caption = "source: data i found somewhere") 

即，因此我们可以在图形的右下方以较小的字体显示数据源.

解决方案

annotation提供了一种简单的方法来向plotly中的图表添加标题:

library(plotly)
plot_ly(x=~hp, y=~mpg, data=mtcars, type="scatter", mode="marker") %>% 
 layout(annotations = 
 list(x = 1, y = -0.1, text = "Source: data I found somewhere.", 
      showarrow = F, xref='paper', yref='paper', 
      xanchor='right', yanchor='auto', xshift=0, yshift=0,
      font=list(size=15, color="red"))
 )

.

Is there a way to add a data source / caption to a chart in Plotly, similar with what can be done in ggplot with the caption argument:

labs(caption = "source: data i found somewhere") 

i.e., so we can display the data source at the bottom right of the graph, in a smaller font.

解决方案

annotation offers a simple way to add a caption to a chart in plotly:

library(plotly)
plot_ly(x=~hp, y=~mpg, data=mtcars, type="scatter", mode="marker") %>% 
 layout(annotations = 
 list(x = 1, y = -0.1, text = "Source: data I found somewhere.", 
      showarrow = F, xref='paper', yref='paper', 
      xanchor='right', yanchor='auto', xshift=0, yshift=0,
      font=list(size=15, color="red"))
 )

.
