QuadMesh datetime doesn't work with plotly backend

Hi, I tried to make a quadmesh with the plotly backend, but the datetime values get converted to numerical.

Also tried bokeh & matplotlib backends, which work fine.

Data:

Plot:

OK, I figured it out.

Just need to convert datetime to an object:

x = xr.DataArray(df.values,dims=("price","date"),
             coords={"date":df.columns.astype('O'),"price":df.index},
             attrs={"long_name":"volume","units":"USDT"})
