Try:?theme(axis.title=element_text(face="bold",size="14",color="brown"),axis.text=element_text(size=14,face="bold")) A.K. How can I increase the size and make bold of the items named under outcome in the example data set? I can make changes to label outcome, but not to individual components(alcohol, coffee etc.. ). ?Likewise, I ?want to make similar changes in the vertical y axis numbers. ggplot(df2, aes(x = exp, y = pinc, ymin = lcinc, ymax = ucinc)) + ? geom_linerange(position=position_dodge(width=0.70)) + geom_point( size = 4.5) ?+ ? ylab("Percent Increase in Mortality") + ? geom_hline(aes(yintercept = 0)) + xlab("Outcome") + ? theme(axis.title=element_text(face="bold",size="14", color="brown")) structure(list(pinc = c(0.456634704861525, -0.0917186505511203, 0.0521212509666302, 0.123917574729071, -0.0152774251113263, 0.414372936947638 ), lcinc = c(0.0652757441790275, -0.51362763597802, -0.365701941999952, -0.293047384315104, -0.430895718383173, -0.00366607270897434), ? ? ucinc = c(0.849524284781999, 0.331979596940069, 0.471696613858441, ? ? 0.542626241433619, 0.402075729259721, 0.83415957680959), ? ? exp = c("smoke", "diabetes", "hyper", "coffee", "alcohol", ? ?
