Change comma and thousand separator in tick labels

Question

In a chart like the one below I wan to change the thousand separator to a dot ".", but I don't know how to use the tickformat parameter in order to get it.

require(plotly)
p <- plot_ly(x=~c(2012,2013,2014,2015,2016), y=~c(1200000,975000,1420000,1175000,1360000), type='bar') %>%
     layout(yaxis = list(title="Income in €", tickformat=",d", gridcolor = "#bbb"), xaxis = list(title="Year"), margin=list(l=80))
p

Answer 1

As far as I know if you use tickformat, separators gets ignored. So you can either specify your tickformat or your separators.

require(plotly)
p <- plot_ly(x=~c(2012, 2013, 2014, 2015, 2016), y=~c(1200000, 975000, 1420000, 1175000, 1360000), type = 'bar') %>%
  layout(separators = '.,', 
         yaxis = list(title='Income in Euro'))
p
