DOC: plot level lines in enet surface #118

Closed mathurinm closed 3 years ago

mathurinm commented 3 years ago

New fig for enet surface. reason: I was surprised by the wild change of gradient at grad_search iter 4. It turns out the lower left part of the cost surface is not as flat as contourf made me think.

WDYT @josephsalmon

I like it better now, but can we get the best of both worlds (I am not found of maps that are all white...) by increasing the number colors, or cliping above (say 35)?

mathurinm commented 3 years ago

Clipping at 35 would be misleading for the 1st iterations.

I tried to keep contourf and increase the number of levels, but it was less clear: image

ok then, let's go for the white version, at least it's clearer where are the countour. Thanks a log @mathurinm .

agramfort commented 3 years ago

I prefer the one with white background
