I am new to pyviz, and I am looking at holoviews for interactive plotting.

I am trying to remove the heatmap (hv.HeatMap) colors, something like color='white', or color=None.

Does anyone know how could I do it?

You can set the fill_alpha=1 and line_alpha=1, e.g.:

hv.HeatMap(((1, 2, 3), (1, 2, 3), np.random.rand(3, 3))).opts(fill_alpha=0, line_alpha=1)
