plot spin texture

[Jerryfufu]

Dear Pyprocar developers,
I want to ask some questions about spin texture.
I'm drawing it with the following parameters
pyprocar.fermi2D(code = 'vasp',dirname='kmesh',energy=0.4,fermi=0.9177,band_indices=[[191]],spin_texture=True,spin_projection='z',clim=[-1,1],arrow_size=3,arrow_density=10,plot_color_bar=True)

And I get the picture, as shown bleow

Because I am a hexagonal lattice, I found that there is a lot of blank aroud GAMMA. Is this because my kmesh is not dense enough(I used kmesh-generator and set [-1,-1,1,1,17,17])? or pyprocar can offer interpolation function?

Best wished
Jerry
