python - Remove holoviews heatmap colors

Question

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?

Answer 1

您可以设置 fill_alpha=1 和 line_alpha=1，例如：

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