comparing spatio-temporal maps

External Email - Use Caution

Hi everyone,
I was wondering how I could see/compare the dynamics of two (or multiple) evoked responses scalp maps.
Is there a way to use ? plot_topomap ? with several evoked objects, so that scrolling a single time cursor would update all scalp maps, and colorscale would handle the global amplitude range (across objects)
or has anyone already written some code that could do that or so?
Many thanks!

hi Fran?oise,

in a notebook you can use a slider using ipywidgets like:

from ipywidgets import interact

@interact(time=(evoked.times[0], evoked.times[-1], 0.01),
          continuous_update=False)
def plot_topo(time):
    evoked.plot_topomap(times=[time], size=3., vmin=-250., vmax=250.)

Hi Alex, thanks for your answer

my question was more about the joint plots actually than on the time slider (which I have using plot_topomap(times=?interactive?) )
basically, how could I synch these two plots for instance ?
thanks!

you need to modify it to plot multiple evoked jointly

hi,

it is currently not implemented. Can you open a feature request issue
on github?
