Hi I am using ggplot to visualise y for a two-factorial group (Bio: 0 and 1) x = 6 years. I was able to adapt the colour of the lines (green and red) and the linetype (solid and dashed). Challenge: my code produces now two legends. One with the colors for the group and one with the linetype for the group. Does somebody have a hint how to adapt the code to produce one legend? Group 0 = red and dashed, Group 1 = green and solid?
MS1<- MS %>% filter(QI_A!="NA") %>% droplevels() dev.new(width=4, height=2.75) par(mar = c(0,6,0,0)) p1<-ggplot(data = MS1, aes(x= Jahr, y= QI_A,group=Bio,color=Bio, linetype=Bio)) + geom_smooth(aes(fill=Bio) , method = "lm" , formula = y ~ x + I(x^2),linewidth=1) + theme(panel.background = element_blank())+ theme(axis.line = element_line(colour = "black"))+ theme(axis.text=element_text(size=18))+ theme(axis.title=element_text(size=20))+ ylab("Anteil BFF an LN [%]") +xlab("Jahr")+ scale_color_manual(values=c("red","dark green"), labels=c("ÖLN", "BIO"))+ scale_fill_manual(values=c("red","dark green"), labels= c("ÖLN", "BIO"))+ theme(legend.title = element_blank())+ theme(legend.text=element_text(size=20))+ scale_linetype_manual(values=c("dashed", "solid")) p1<-p1 + expand_limits(y=c(0, 30)) kind regards Sibylle ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
