Aligning line plots and information on second y-axis

[amegbor]

Hello everyone,

I'm seeking assistance in aligning my coefficient plots with the text information displayed on the second y-axis on the right. I've attempted to achieve this using the code below, and here's the current result. I also experimented with manipulating the values in breaks = as.vector(outer(c())), but it seems to worsen the alignment of the plot. Any help or suggestions will be greatly appreciated. I can provide the data if needed. Thank you.

ggplot(df, aes(x=mean, y = Exposure, colour=Models)) + scale_color_brewer(palette="Set1", breaks=c("Model 1","Model 2","Model 3", "Model 4","Model 5")) + geom_vline(aes(xintercept = 0), size = .25, linetype = "dashed") + geom_point(position = position_dodge(width=.75)) + scale_x_continuous(breaks = c(-0.1, 0.001, 0.03, 0.05, 0.08)) + geom_errorbarh(aes(xmin = lci, xmax=uci), position=position_dodge(width=.75), height=0) + labs(x="Posterior Mean", y="Exposure", colour="Models") + guides( y = guide_axis_nested(delim = "&", n.dodge = 1), y.sec = guide_axis_manual( breaks = as.vector(outer(c(-0.18125, -0.09375, 0.09375, 0.18125, 0.36875), 1:2, "+")), labels = rev(df$estimates) ) ) + theme_classic() + theme( axis.text.y.left = element_text(margin = margin(r = 5, l = 5)), ggh4x.axis.nesttext.y = element_text(margin = margin(r = 6, l = 6)), ggh4x.axis.nestline.y = element_blank())

I think it might be a matter of just choosing the appropriate values.
You have width = 0.75 with n = 5 groups, so each group should be spaced 0.75 / 5 == 0.15 y-axis units apart.
So the values for the manual axis should be:

as.vector(outer(c(-0.3, -0.15, 0, 0.15, 0.3), 1:2, "+"))

Thank you. it worked.
