colors - R : stat_smooth error cause by sufficient unique values -


i have dataset, , want show figure using stat_smooth().

first, can show age vs scored_probabilities (male) figure, looks this:

names(dataset2) <- sub(pattern=' ', replacement='.', x=names(dataset2))  dataset3 <- subset(dataset2,gender== 'male') #patterns vs age d <- ggplot(dataset3, aes(y=scored.probabilities, x=jitter(as.numeric(age)), colour=factor(patterns))) d + stat_smooth() +scale_colour_brewer(palette="set3")

man

but when changing male female, error occurs:

#female dataset4 <- subset(dataset2,gender== 'female')  #patterns vs age d <- ggplot(dataset4, aes(y=scored.probabilities, x=jitter(as.numeric(age)), colour=factor(patterns))) d + stat_smooth()+scale_colour_brewer(palette="set3")  error in smooth.construct.cr.smooth.spec(object, data, knots) :    x has insufficient unique values support 10 knots: reduce k.

second, "set3" color seems not enough plot. color set can solve it?

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
