K3D-tools / K3D-jupyter

K3D lets you create 3D plots backed by WebGL with high-level API (surfaces, isosurfaces, voxels, mesh, cloud points, vtk objects, volume renderer, colormaps, etc). The primary aim of K3D-jupyter is to be easy for use as stand alone package like matplotlib, but also to allow interoperation with existing libraries as VTK.

Hi @mushroomfire

At this moment colorbar is not customizable. It is rather simple tool. Adding a label can be manage by text2d. Based on examples/volume_renderer.ipynb:

embryo = k3d.volume(volume_data.astype(np.float16), 
                    color_map=np.array(k3d.basic_color_maps.BlackBodyRadiation, dtype=np.float32), 
                    bounds=bounds)

plot = k3d.plot()
plot += embryo
plot += k3d.text2d("Color legend:", position=(0.02, 0.45), is_html=True, label_box=False, color=0)
plot.display()

Will results with: image

If that is not sufficient please share more what you need
