Prevent plotly from clipping plot

Dear Plotly users

I have a figure generated with matplotlib and visualized by plotly for iphython.

I have multiple subplots in a Figure and would like to prevent plotly from clipping the graphs in y direction. If the graph goes beyond the y limit it should still be plotted. In matplotlib has something like clip_on=False. How can it be done in Plotly.

Thanks for any hint.
