confusing API for heatmap legend

When trying to customize the legend for a heatmap I would expect that to be done through the layout similar to other trace types.

plot_ly(
  z = volcano, 
  type = "heatmap",
) %>%
  layout(
    legend = list(
      title = list(
        text = "custom title"
      )
    )
  )

After digging around for a while and examining the output of plotly_build() %>% plotly_json() I found that this is done through the top level colorbar instead.

plot_ly(
  z = volcano, 
  type = "heatmap",
  colorbar = list(
    title = "custom title"
  )
) 

I would say that if the interface for this needs to be different than for other traces, that should be documented on the heatmap page. Even better may be to standardize the approach so that users always know to go to layout for this type of thing.

I'm also curious why colorbar title is shown as a deprecated attribute from schema().

Comienza con la página de mapas de calor de R enlazada en el issue e inspecciona los ejemplos documentados junto con la salida de plotly_build() y plotly_json() descrita allí. Documenta que la personalización de la leyenda del mapa de calor utiliza el colorbar de nivel superior, incluido el detalle de la obsolescencia de schema(); el trabajo estará completo cuando una persona nueva pueda encontrar y seguir la interfaz documentada.
