Hello,

I am trying to make a bar polar chart for spindle orientation in a quarter circle shape. My data has two columns, "Angle" and "Percentage". I used plotly package in R and the below codes to make it:

library("plotly")
p <- plot_ly(
  type = 'barpolar',
  r = c(54.7, 32.6, 8.4, 10.4, 30.6),
  theta = c(0, 10, 20, 30, 40)) %>% 
    layout(
    polar = list(
      radialaxis = list(
        visible = T,
        range = c(0,60)
      ),
      sector = c(0,90),
      radialaxis = list(
        tickfont = list(
          size = 10
        )
      ),
      angularaxis = list(
        tickfont = list(
          size = 10
        )
      )
    )
)

However, I need to change some features of the created bar polar chart. I searched a lot but I could find how to modify them. May I kindly ask you to help me in my below questions:

1) How to modify the interval of bins? I mean, in my current chart, angles are divided to 0, 15, 30, 45, 60, 75, and 90 degrees. The interval of each bin is 15 degree. But, I need to change this interval to 10 and make the angle divisions to 0, 10, 20, 30, 40, 50, 60, 70, 80, and 90. How can I do that?

2) How can I change the colour of bars? Now all five bars are blue, but I want to change the blue colour, for example, to black, red, or any colour.

I would highly appreciate your great and valuable help. Best wishes.
