I am making a simple line plot using ggplot2:
ggplot(data=GrayStandard, aes(x=Exposure, y=MeanLinear.VIS,
group=Standard, colour=Standard ))+
geom_line(size=1.5)+ coord_cartesian(xlim=c(0,30))+
scale_color_manual(values=c(palette))+ylab("Mean value")+ xlab("Exposure")+
theme(panel.background = element_rect(fill='white'), axis.line = element_line(colour="black"))+
theme(text = element_text(size=15,face= "bold",colour="black"), panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),axis.line = element_line(colour="black"))+
theme(axis.text=element_text(size=13,colour="black"))#+theme(legend.position="none"))
But I need the x axis to be different than the default display because it has a lot of very small numbers at the beginning (left) and large numbers at the end (right). Any suggestions on how to change the whole axis to one scale? say every 0.2 units?
Thanks!
