I am trying to use a custom HoverTool with datashader with the following code :
hover = HoverTool(tooltips=[("Wind speed", "@Wind_Speed")]) rasterize(mesh, precompute=True, aggregator=dsh.mean("Wind_Speed"), dynamic=False, x_range=x_range, y_range=y_range,height=height, width=width).opts(cmap=highCmap, colorbar=True, tools=[hover])
I tried to remove the aggregator but it doesn’t work too.
When I hover I’ve got
“Wind speed: ???”
I just want to know if it should be possible to use a custom HoverTool or if I’m doing it wrongly
