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.
