Cursor issue interacting with plotly plots

[johncarew]

I have created several plots including a histogram, a surface plot, a boxplot, and a scatterplot, in a JS Reveal presentation. When I knit the presentation and open it in a browser the plots display, but when I try to select a data point to read the values of that point, the point directly beneath the cursor is not selected. Instead, a point up and to the left of the cursor is selected. This is also happening with a line graph and a scatter plot I have created using the htmlwidgets package. Is there a way that I can select data that is directly under the cursor? Any help would be greatly appreciated!

```{r}
library(plotly)
p <- plot_ly(midwest, x = percollege, color = state, type = "box")
p
```

This is a sample r chunk that creates a histogram, but I cannot select the data directly beneath the cursor.

I think this was fixed in c500425.

I'm facing the issue described here: rstudio/revealjs#47

Consider the following minimal document:

---
output: revealjs::revealjs_presentation #works with html_document
---

```{r plotly, message = FALSE, echo = FALSE}
library(ggplot2)
library(plotly)
g <- ggplot(mpg, aes(x = cty, y = hwy, colour = as.factor(cyl))) +
  geom_point()
ggplotly(g)
```

When using reveal.js, the cursor needs to be placed above and to the left of the points for the tooltip to trigger - rather than on top of them. This doesn't occur when using the default html_document style.

Having the exact same problem as patzaw. Knitting revealjs presentations with plotly objects seems to make the cursor behave in a weird manner - to select points I actually have to hover to the top and left of them.

+1 having the same problem with plotly + revealjs

I think the code below solves the problem.

  revealjs::revealjs_presentation:
    reveal_options:
      minScale: 1.0
      maxScale: 1.0

@paulofelipe your solution worked for me.
Thanks!

For anyone still coming to this issue, the dev version of plotly is the one to use to solve this (specifically for revealjs) as it updates the version of plotly.js which has the fix for this.
