Coordinates in degree in Rose plot

I want to plot the following coordinates in a rose plot, so I get something that looks like a compass, with a representation for the element at the respective direction. I have tried different bins, but did not get the right result.

   a= [30,
      180,
      40,
      260,
      310,
      ]

rose(a,360)

rose theta input is expressed in radians (most of trig-related matlab functions are in radians).

You can try this:

rose(a.*(pi/180),360)
