geom_line not plotting when setting tooltip argument with ggplotly

问题

I'm trying to plot with ggplot and it was working perfectly fine but when I add in tooltip modifiers it breaks the ggplot. Here's the code for ggplot:

ggplot() +
      # mean in blue, must have label in both geom_point and geom_line to show up??
      geom_point(data = sumsd, aes(x = Year, y = Mean, text = paste("Income Required Mean:", round(meanir, 2))), color = "blue") +
      geom_line(data = sumsd, aes(x = Year, y = Mean, text = paste("Income Required Mean:", round(meanir, 2))), color = "blue") +

      # median in red
      geom_point(data = sumsd, aes(x = Year, y = Median, text = paste("Income Required Median:", round(medianir, 2))), color = "red") +
      geom_line(data = sumsd, aes(x = Year, y = Median, text = paste("Income Required Median:", round(medianir, 2))), color = "red") +

      # BMR Mean in green
      geom_point(data = sumbmr, aes(x = sumbmr$year, y = BMRMean, text = paste("Income Required Mean:", round(meanir, 2))), color = "green") +
      geom_line(data = sumbmr, aes(x = sumbmr$year, y = BMRMean, text = paste("Income Required Mean:", round(meanir, 2))), color = "green") +

      # BMR Median in Orange
      geom_point(data = sumbmr, aes(x = sumbmr$year, y = BMRMedian, text = paste("Income Required Median:", round(medianir, 2))), color = "orange")  +
      geom_line(data = sumbmr, aes(x = sumbmr$year, y = BMRMedian, text = paste("Income Required Median:", round(medianir, 2))), color = "orange") +

      xlab('Date') +
      ylab('Affordability (%)')  

When you plot this, not only do lines not work, but there is double of everything.

The moment you remove the "text =" portion, it works perfectly fine.

I'm trying to use solutions from other SO questions but the issue is my situation is unique since I'm plotting from two different data frames. I am thinking one solution is combining the data frames and using group but I am unsure how to use group correctly in this situation.

dput(sumsd) looks like this:

You need to use label and not text in your geoms.

However, you may find challenges (as I have) in producing production quality plots using plotly::ggplotly, it is not quite mature and I've found issues with positioning and labels that aren't quite ready for prime time yet.

Alternate solution

Additionally, I offer a full plotly solution, which circumvents the shortcomings in the plotly::ggplotly approach. Plot output below and the reproducible source for both following at the bottom.

回答2:

The solution I found was to add a column called group and to number the first data frame as 1 in the group column and number the second data frame as 2 in the group column. Then, I merged the two data frames into one and added "group = group" in the aesthetics of ggplot. Here is the code:

Year <- sumsd$year
    Mean <- sumsd$Mean
    Median <- sumsd$Median
    sumbmr <- bmr %>% group_by(year)%>%summarise(Mean=mean(ipm), Median=median(ipm), meanir = mean(ir), medianir = median(ir))
    BMRMean <- sumbmr$Mean
    BMRMedian <- sumbmr$Median

    namevector4 <- c("group")
    sumbmr[,namevector4] <- 2

    sumsd$meanbmr = BMRMean
    sumsd$medianbmr = BMRMedian
    sumsd$meanbmrir = sumbmr$meanir
    sumsd$medianbmrir = sumbmr$medianir

ggplot(sumsd, group = group) +
      # mean in blue
      geom_point(aes(x = year, y = Mean, text = paste("Income Required Average:", round(meanir, 2))), group = 1, color = "blue") + 
      geom_line(aes(x = year, y = Mean, text = paste("Income Required Average:", round(meanir, 2))), group = 1, color = "blue") + 

      #median in red
      geom_point(aes(x = year, y = Median, text = paste("Income Required Median:", round(medianir, 2))), group = 2, color = "red") + 
      geom_line(aes(x = year, y = Median, text = paste("Income Required Median:", round(medianir, 2))), group = 2, color = "red") + 

      # BMR Mean in green
      geom_point(aes(x = year, y = meanbmr, text = paste("BMR Income Required Average:", round(meanbmrir, 2))), group = 3, color = "green") + 
      geom_line(aes(x = year, y = meanbmr, text = paste("BMR Income Required Average:", round(meanbmrir, 2))), group = 3, color = "green") + 

      # BMR Median in orange
      geom_point(aes(x = year, y = medianbmr, text = paste("BMR Income Required Median:", round(medianbmrir, 2))), group = 4, color = "orange") + 
      geom_line(aes(x = year, y = medianbmr, text = paste("BMR Income Required Median:", round(medianbmrir, 2))), group = 4, color = "orange") + 
      xlab('Date') +
      ylab('Affordability (%)') 

Chart seemed to function fine after using this code

Hopefully this will help someone out
