您好我使用plotly制作热图。代码是：

     plot_ly(z = ~df$MonetaryClass, 
        x = ~df$RecencyClass, 
        y = ~df$FrequencyClass, 
        type = "heatmap") %>% 
  colorbar(title = 'Monetary Class',
           limits = c(1,5), 
           tickmode = 'array', 
           tickvals = c(1,2,3,4,5)) %>%
  layout(title = "RFM Analyse",
         xaxis = list(title = 'Recency Class',
                      tickmode = 'array',
                      tickvals = c(1, 2,3,4,5),
                      ticktext = c(1, 2, 3, 4, 5)
         ),
         yaxis = list(title = 'Frequency Class',
                      tickmode = 'array',
                      tickvals = c(1, 2,3,4,5),
                      ticktext = c(1, 2, 3, 4, 5)
         )
  )

以下是我的100个数据框的示例，以及dput()的信息：

     structure(list(RecencyClass = c(3, 4, 4, 3, 4, 4, 1, 4, 3, 4, 
4, 2, 1, 3, 5, 5, 2, 1, 4, 1, 3, 1, 4, 2, 2, 1, 4, 5, 2, 4, 5, 
1, 1, 1, 3, 3, 3, 4, 1, 3, 1, 3, 1, 3, 2, 5, 2, 1, 4, 1, 5, 2, 
4, 4, 2, 2, 5, 3, 1, 3, 3, 5, 2, 2, 4, 4, 2, 2, 5, 2, 2, 2, 5, 
3, 2, 1, 1, 2, 5, 2, 1, 1, 2, 1, 4, 2, 3, 2, 2, 1, 1, 2, 2, 4, 
5, 3, 5, 5, 5, 5), FrequencyClass = c(4, 5, 1, 3, 5, 5, 3, 1, 
5, 3, 1, 3, 4, 1, 3, 2, 1, 2, 5, 1, 1, 4, 3, 2, 3, 1, 4, 4, 2, 
4, 4, 5, 1, 1, 3, 4, 4, 3, 2, 4, 1, 2, 1, 2, 1, 4, 1, 1, 2, 1, 
3, 1, 3, 2, 2, 4, 2, 5, 1, 2, 1, 2, 1, 2, 1, 3, 1, 3, 5, 2, 1, 
4, 5, 1, 1, 3, 1, 1, 5, 4, 4, 2, 5, 1, 4, 1, 5, 2, 1, 1, 1, 3, 
5, 5, 4, 4, 4, 3, 4, 2), MonetaryClass = c(5, 5, 3, 4, 5, 3, 
1, 2, 3, 3, 1, 2, 3, 1, 4, 3, 2, 3, 5, 2, 1, 4, 1, 3, 2, 3, 5,

2, 4, 3, 1, 2, 4, 2, 5, 1, 5, 1, 1, 1, 3, 3, 2, 1, 5, 2, 4, 5, 
2, 1, 4, 2, 1, 3, 5, 2, 1, 5, 5, 5, 2, 4, 1, 5, 1, 5, 1, 4, 1, 
2, 1, 1, 5, 3, 5, 2, 2, 4, 3)), .Names = c("RecencyClass", "FrequencyClass", 
"MonetaryClass"), row.names = c(24908L, 34164L, 27970L, 23648L,

看起来像这样：

正如你所看到的，我有25个盒子洞察我的矩阵。是否可以在每个框中编写自选文本？例如，在框“1”频率和“1”新近，左下角的蓝黑色像“我喜欢啤酒”。或者在“5”和“5”右上角的黄色，类似“我喜欢CSGO”。 我用text尝试了它，但它对我不起作用。

您可以通过add_annotations添加文字。

  • 指定x和y坐标（在下面的示例中，相对于x和y轴，通过xref = 'x'和yref = 'y'）
  • 通过text
    • 添加文字
  • 使用showarrow = FALSE
    • 删除默认箭头

enter image description here 

anno_x <- c(1, 5)
anno_y <- c(1, 5)
anno_text <- c('I like beer', 'I like CSGO')

p <- plot_ly(
  x = c(1:5), 
  y = c(1:5),
  z = matrix(rnorm(9), nrow = 5, ncol = 5),
  type='heatmap') %>% add_annotations(x = anno_x, y = anno_y, text = anno_text, xref = 'x', yref = 'y', showarrow = FALSE, font=list(color='black'))

p
