Share values between traces (like Bokeh ColumnDataSource) of Plotly?

Hi,

Are there options in Plotly to share values between traces?

Example:
Input: dataframe with N columns and one reference.
Output: N subplots

In Bokeh it is very easy to build ColumnDataSource and define that Col_1, Col_2… Col_N can share all the same index axis, without N times duplicating the JSON data.
In Plotly using Python, the only way I know it is to pass 10 times the index and this increase unnecessary my output file.

Are there options to share axis values between traces?

Thanks,
Velizar
