Plotly ggplot stacked bar chart disappear when leg

Question

I'm not sure why but my stacked bar chart disappears instead of falling to the axis when the legend is clicked. I've attached a screenshot of the example that I copied from the plotly website and the code are as follows:

library(plotly)

DF <- read.table(text="Rank F1     F2     F3
1    500    250    50
2    400    100    30
3    300    155    100
4    200    90     10", header=TRUE)

library(reshape2)
DF1 <- melt(DF, id.var="Rank")

p <- ggplot(DF1, aes(x = Rank, y = value, fill = variable)) +
  geom_bar(stat = "identity")

p <- ggplotly(p)

Stacked Bar Chart disappears when legend is clicked

Can anyone assist me with this?

You can use the plotly API directly, rather than ggplotly, then it works as expected:

plot_ly(DF1) %>%
  add_bars(~Rank, ~value, color=~variable) %>%
  layout(barmode = 'stack')

If you need to also embed a static version of the plot in an R Markdonw document, you can use the export() function to create a static version:

---
title: "Untitled"
output: word_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

Here's a barchart:

```{r chart}
library(plotly)
library(reshape2)

DF <- read.table(text="Rank F1     F2     F3
                 1    500    250    50
                 2    400    100    30
                 3    300    155    100
                 4    200    90     10", header=TRUE)
DF1 <- melt(DF, id.var="Rank")

p = plot_ly(DF1) %>%
  add_bars(~Rank, ~value, color=~variable) %>%
  layout(barmode = 'stack')
export(p)
```
