Cannot Modify y-axis Limits for evoked.plot_joint function

The documentation states:

ylim : dict | None
    Y limits for plots (after scaling has been applied). e.g. 
    ylim = dict(eeg=[-20, 20]) Valid keys are eeg, mag, grad, 
    misc. If None, the ylim parameter for each channel equals 
    the pyplot default.

You are providing a tuple, I’m actually surprised this is not raising an error.
Try providing dict(eeg=(-10, 10) (in case of EEG data, change the type to what you need, note that CSD transformed data has the type csd).
