Show last y value on tick label side

Hello! How can I show last y value on tick label side like this one Dropbox? I tried fig.add_annotation but it can’t position on the y tick label side.

Hi @JackTang ,

based on your image, is the result should display something like this ?

you can set xref = "paper" attribute in annotation, then adjust the x attribute value over 1 for example above I use x=1.05, and set xanchor='right', yanchor='middle'.

fig.update_layout(annotations=[dict(
        xref='paper',
        x=1.05,
        y=last_point,
        xanchor='right', 
        yanchor='middle',
        text='{}'.format(last_point), 
        showarrow=False,
        font=dict(size=16,color='red')
        )])
