How to add significant cut off in manhattan plot

Question

[Kumar]

Hi, I need to add significant cut off value (<0.01) in my circular manhattan plot. Please see following code that I am using for plotting and link of plot.

CMplot(manhat,plot.type="c",r=0.6, col=c("grey30","grey60"),chr.labels=c("Chr1", "Chr2",  "Chr3", "Chr4", 
"Chr5","Chr6","Chr7","Chr8","9","Chr10","Chr11","12","Chr13","Chr14"),

 LOG10=TRUE, cir.chr.h=0.5,amplify=TRUE,threshold.lty=c(1,2),threshold.col=c("red",
"blue"),

 signal.line=1,signal.col=c("red","green"),chr.den.col=c("darkgreen","yellow","red"),
 outward=FALSE,file="jpg",dpi=600,file.output=TRUE,verbose=TRUE,width=10,height=10)

How exactly do you envision it to be added? Just as a number printed on the plot? Or via a line/asterisk/....?

Can you please elaborate your answer, I am not certain to understand?

What is your expected plot look like?

(please format your code, use some spaces, newlines.)

Here, is a example excel file for manhattan plot, that I need to put significant cut off values at each bar on circular manhattan plot.

It is still unclear what you want. Please try, and be it by hand in Powerpoint, to make a representative picture so people understand what you would like to do.

Please see How to add images to a Biostars post to add your images properly. You need the direct link to the image, not the link to the webpage that has the image embedded (which is what you have used here)
