Re: How to set AnnoArrow a color

Hi Mary,
   Thanks for your help.
   I have checked the examples, I found that all of them use the function gsn_vector. But I am using the function gsn_csm_vector_scalar_map_ce, I also set
vcMonoLineArrowColor = False ;
But it is still not work. Do you think it is not work for the function gsn_csm_vector_scalar_map_ce?

But I would like its color can vary with the vaule of vcRefMagnitudeF's variation just as the arrows color in the vector field. I have setted the vcRefAnnoArrowUseVecColor = True and vcUseScalarArray= True , but the annotation arrow's color still is black. They look like not work.
