R plotly disable default hovertext and only display customized text

Question

I am struggling to disable the default hovertext. I have added custom hovertext but the default is still showing besides the custom text. I have tried hoverinfo = 'none' and hoverinfo = ''. In the screenshot above the arrow points to the default hover text. Is there a way to disable that text?

Here is my code:

temp <- structure(list(therapy_class = structure(c(1L, 1L, 1L, 1L, 1L, 
1L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 3L, 3L, 4L, 4L, 4L,

7L, 7L, 7L, 7L, 7L, 8L, 8L, 8L, 8L, 8L, 8L), .Label = c("ALK Inhibitors",

Answer 1

plot_ly(
    data = temp,
    y = ~value,
    x = ~Year_month,
    color = ~therapy_class,
    name = ""
)

Needed to pass name parameter as "". It was using the default and using that in hover info.
