Olá lista! Alguém saberia como incluir dois gradientes de cores no mesmo conjunto de dados? No ggplot? Tentei dividir o conjunto de dados, mas não rolou. meu codigo foi:
dat1 change values 1 -10 0.00 2 -9 0.50 3 -8 0.20 4 -7 0.30 5 -6 0.00 6 -5 0.00 7 -4 0.61 8 -3 0.40 9 -2 1.00 10 -1 0.80
dat2 change values 1 5 0.61 2 3 1.00 3 10 0.50 4 2 0.00 5 7 0.00 6 6 0.50 7 8 0.00 8 10 0.30 9 6 0.61 10 6 0.20
p = ggplot() + xlim(-10, 10) + ylim(0,1) + labs(x= "change", y= "values")+ geom_point(data=dat1, aes(x=change, y=value, color=value), shape=19, size=3, alpha=0.5)+ scale_color_gradientn(colours=c("#FC4013","#FED246")) p1 = p+geom_point(data=dat2, aes( x=change, y=value, color=value), shape=19, size=3, alpha=0.5)+ scale_color_gradientn(colours=c("#5CB0FD","#4DE775")) + theme(axis.text.x = element_text(size=18,colour='grey8'), axis.text.y = element_text(size=18,colour='grey8'), axis.title.x = element_text(size=18,colour='grey8'), axis.title.y = element_text(size=20,colour='grey8'), strip.text.x = element_text(size=18,colour='grey8'), strip.background = element_rect(fill="transparent"), legend.position="none", legend.text=element_blank(), legend.title=element_blank(), legend.background = element_rect(fill="grey98", size=1, linetype="solid"), panel.background=element_rect("grey98")) p1 + geom_vline(xintercept = 0,colour="grey68",linetype='twodash', size=2)+ geom_hline(yintercept = 0.5, colour="grey78") -- *Priscila Lemes, * *PhD in Ecology and Evolution* *- UFG* <http://www.wix.com/rdloyola/lab> Post Doctoral, Department of Zoology, IB, UNESP - Rio Claro - São Paulo - Brazil http://lattes.cnpq.br/7228776843625214 Skype: plemes_
