twin y axis, adding grids

Using bokeh 0.12.1.

I have a chart with twin Y axis, one on each side of it.

g1 = figure(tools=tools, x_range=labels, y_range=Range1d(0,scale_a))
extra_axis = LinearAxis(y_range_name='extra_y')
g1.extra_y_ranges = {'extra_y': Range1d(0, scale_b)}
g1.add_layout(extra_axis, 'right')

[...glyphs added to g1...]

Having a named LinearAxis (extra_axis) allows me to use two different colors for the major labels corresponding to the glyph colors:

g1.yaxis.major_label_text_color = primary_color
extra_axis.major_label_text_color = secondary_color

I can similarly add horizontal grid lines on the major labels, color coded for the main yaxis (ygrid):

g1.ygrid.grid_line_alpha = 0.5
g1.ygrid.grid_line_color = primary_color

But I can’t figure out how to enable a secondary horizontal set of gridlines corresponding to the secondary y axis. Is there a secondary ygrid? Can’t seem to figure out the name.

Thanks,

Francois

Spitballing, I figured I’d need to manage the secondary grid, and tried:

extra_grid = Grid(ticker=extra_axis.ticker, dimension=1)
extra_grid.grid_line_color = secondary_color
extra_grid.grid_line_alpha = 0.5
g1.add_layout(extra_grid)

But no joy...
