plot_erp: problem with curve endpoints

[EmmanuelleKris]

Hello,
When I plot the effects, the extreme points of the curves are connected.
Do you know why this is?

fig2= Figure()
eff = effects(Dict(:eventname => ["Conflict", "Fixation"]), m) 
plot_erp!(fig2[1,1],eff; mapping = (; color = :eventname))
fig2

try this:

plot_erp!(fig2[1,1],eff; mapping = (; color = :eventname,group =:eventname))

I forwarded this as an issue to UnfoldMakie

mh okay - your effects call is now something like this?
eff = effects(Dict(),m)

Hello,
I'm back ;).
I tried
eff = effects(Dict(),m)
and I get the same issue

When I plot directly the results, I get a good figure:

plot_erp!(fig1[1,1],
    results,
    mapping = (; color = :eventname => "Event"),
    axis = (title = string("model",string.(channelslabel[idxch])), xlabel = "Time [s]"),
)

But I have the same type of problem when I plot results if, this time, I have splines in the model for“Fixation” event. The previous example was a model without splines (only with intercept).

Hey Bene is on holiday, so I'll try to help you out =)

For the first issue:

Hello, I'm back ;). I tried eff = effects(Dict(),m) and I get the same issue

The plot looks a lot like you just used plot_erp!(fig2[1,1],eff), i.e. without any group or color. Have you tried this?:

eff = effects(Dict(),m)
plot_erp!(fig2[1,1],eff; mapping = (; color = :eventname,group =:eventname))

As for the second issue:

But I have the same type of problem when I plot results if, this time, I have splines in the model for“Fixation” event. The previous example was a model without splines (only with intercept).

You might need to indicate that your coefficients are your group:

plot_erp!(fig1[1,1],
    results,
    mapping = (; color = :eventname => "Event", group = :coefname),
    axis = (title = string("model",string.(channelslabel[idxch])), xlabel = "Time [s]"),
)

Ok, it works! Thanks! :)

Glad to hear! I'll close the discussion then =)
