title: Change axis of plotly polar plot
body: <p>I am playing with Plotly tools using python and I have made a polar plot as seen below using some dummy data:</p>
  
  <p><a href="https://i.stack.imgur.com/kvjrn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kvjrn.png" alt="enter image description here"></a></p>
  
  <p>I would like to alter the axis so that the data I have (goes from around 20 to 50) is mapped to the entire 360° of the plot. Is there a way of doing this using a readymade command or do I need to write a function where you set the limits then map those numbers to degrees before changing axis labels. I have been looking through stack exchange but I can only find ways of changing it to radians. </p>
