mjs_add_mouseover: Doesn't work with mjs_point

[tinyheero]

Hi,

I am testing out the mjs_add_mouseover and was using the test example as an template. I've noticed that it adds custom text for mjs_line(), but doesn't seem to work with the mjs_point()? For example, considering the following data:

dat <- data.frame(value=rnorm(n=30, mean=5, sd=1),
                  value2=rnorm(n=30, mean=4, sd=1),
                  test = c(rep(c('test', 'test2'), 15)))

dat %>%
  mjs_plot(x = value, y = value2) %>%
  mjs_line() %>%
  mjs_add_mouseover("function(d, i) {
                $('{{ID}} svg .mg-active-datapoint')
                    .text('custom text : ' + d.test + ' ' + i);
                 }")

Custom text is added with the d.test, but if I do the following:

dat %>%
  mjs_plot(x = value, y = value2) %>%
  mjs_point() %>%
  mjs_add_mouseover("function(d, i) {
                $('{{ID}} svg .mg-active-datapoint')
                    .text('custom text : ' + d.test + ' ' + i);
                 }")

I get an undefined for the custom test? Am I missing something here?

Hi,

I was wondering if you could point me in the right direction as to where I could look to fix what seems like a bug. Really looking forward to get this to work for scatterplots, but unfortunately I can't get it working...

Thanks!

Hi, first, thank you for the package, which has great value. I run into exactly the same problem as tinyheero and it would be wonderful if the issue could be solved. Best, Holger.

Taking a look this weekend

I agree this would be very helpful. Does anyone know if it works in the native MetricsGraphics.js utility or is a bug specific to this R package? Thanks!

Take a look here: https://github.com/mozilla/metrics-graphics/issues/308

This is an issue with metrics-graphics, unfortunately, not the package.

Try using d.point.test vs d.test.

Thanks for looking at this. Works for me. Excited to be able to use this.

Thanks for the solution, that works also fine for me! Love it.
