Choropleth colorbar y and len arguments have no effect.

[jakehoare]

The code below is based this example plotting world GDP.

It attempts to modify the colorbar using x, y, and len arguments.

The x argument has an effect and moves the colorbar horizontally. y and len have no impact, so the vertical position and length cannot be altered.

library(plotly)

df <- read.csv('https://raw.githubusercontent.com/plotly/datasets/master/2014_world_gdp_with_codes.csv')

# specify map projection/options
g <- list(
    showframe = FALSE,
    showcoastlines = TRUE,
    projection = list(type = 'Mercator')
)

p <- plot_geo(df, locationmode = 'country names') %>%
    add_trace(
        z = ~GDP..BILLIONS., color = ~GDP..BILLIONS., colors = 'Blues',
        locations = ~COUNTRY
    ) %>%
    colorbar(title = 'GDP Billions US$',
             x = 0.5,
             len = 0.1,
             y = 0.1
             ) %>%
    layout(
        geo = g,
        margin = list(l=0, r=0, t=0, b=0, pad=0)
    )

print(p)

Same issue here, several arguments to colorbar() seem to have no effect (except x). This worked with plotly 3.6.0.

library(plotly)
p <- plot_ly(z = volcano, type = "surface")
colorbar(p, x = 0, y = 0, yanchor = "bottom")
