Unable to change the color label

[StanleyAgu1]

I have a problem with the color label.

I want to remove the white color of the planets on my plot, but I keep getting errors. this is my script

`def plot_holoviews(mesh, data, wireframe=False, cmap=None, proj='pc', data_name='data',clabel=None, levels=None):

elem2 = mesh.elem[mesh.no_cyclic_elem]
data = np.ma.masked_equal(data, 0)

verts = pd.DataFrame({'Longitudes':mesh.x2, 'Latitudes':mesh.y2, 'data':data})
tris = pd.DataFrame({'v0':elem2[:,0],'v1':elem2[:,1], 'v2':elem2[:,2]})
fesom_mesh = gv.TriMesh((tris, verts), crs=crs.PlateCarree())
if wireframe:
    verts2 = pd.DataFrame({'Longitudes':mesh.x2, 'Latitudes':mesh.y2})
    trimesh = gv.TriMesh((tris, verts2), crs=crs.PlateCarree())
    wireframe_plot = datashade(trimesh, interpolation=None, cmap=['black'])

if proj == 'pc':
    projection=crs.PlateCarree()
    width=800,
    height=500,
    y_range=(-80,90)
elif proj == 'np':
    projection=crs.NorthPolarStereo()
    width = 500,
    height = 500,
    y_range=(60,90)
elif proj == 'sp':
    projection=crs.SouthPolarStereo()
    width = 500,
    height = 500,
    y_range=(-90,-30)

if cmap is None:
    cmap=cmo.balance
    
main_plot = rasterize(fesom_mesh, interpolation=None, y_range=y_range).opts(
                    tools=["hover"],
                    width=width[0],
                    height=height[0],

projection=projection,

                    colorbar=True,
                    cmap=cmap,
                    colorbar_position="bottom",
                    clabel=clabel,
                    fontscale=1.3,
                    color_levels=levels
                )
if wireframe:
    return main_plot * gv.feature.coastline() * wireframe_plot
else:
    return main_plot * gv.feature.coastline()`

After Loading my data, I did this;

levels=[-5,-4,-3,-2,-1,0,1,2,3,4,5] and the this;
plot_holoviews(mesh, data0, clabel="sea surface temperature", levels=levels)

I don't know what the problem is, can someone help me with this?

Thank you

@StanleyAgu1 This code is not related to pyfesom, it's probably more of the geoviews issue.

It's also not clear from your post what modules you are using and what errors you are having. Notebook or script with minimum example would be helpful.
