r - 如何在plotly R中的绘图上添加文本框？

Question

我想在用plotly生成的图上添加一个文本框或信息文本。 现在看来是这样。 without text

我想用文本框制作如下(不需要圈出:)))。

with text-box

到目前为止的代码:

p <- plot_ly(data=data.mosann, x = ~Combined, y = ~Actual)%>%
  layout(shapes=list(type='line', x0= 0, x1= 235, y0=0, y1=235, line=list(color='red',width=3)),
         title = 'Scatter Plot Measurements-Combined Improvements MinT',
         xaxis = list(title = "Combined MinT", showgrid = TRUE),
         yaxis = list(title = "Measurements", showgrid = TRUE))
p

试试这个。根据您想要文本的位置更改布局注释的 x 和 y。

p <- plot_ly(data=data.mosann, x = ~Combined, y = ~Actual)%>%
  layout(xaxis = ~Combined, yaxis = ~Actual, 
         annotations = list(text = "YOUR TEXT HERE",  x = 200, y = 30,showarrow=FALSE ),
         shapes=list(type='line', x0= 0, x1= 235, y0=0, y1=235, line=list(color='red',width=3)),
         title = 'Scatter Plot Measurements-Combined Improvements MinT',
         xaxis = list(title = "Combined MinT", showgrid = TRUE),
         yaxis = list(title = "Measurements", showgrid = TRUE))
