Hi,

Thanks for reading. I have made a 3D plot with rgl, and I am unable to change the width of the bars, the number of breaks of an axis and how to suppress the numbering of an axis. Anyone has any idea? Please find the code attached.

`library(rgl)`

# create some data

X=c(10,8,9,7,6,5,4,3,2,1) # Patient ID

Y=c(115,60,100,72,100,96,95,65,62,32) # Days

Z=c(-100,-60,-60,-30,-15,-10,15,35,40,50) # % RECIST

`# create an empty plot with the good dimensions`

plot3d(1,1,1, type='n', xlim=c(min(X),max(X)), ylim=c(min(Y),max(Y)), zlim=c(min(Z),max(Z)), xlab="", ylab="", zlab="", axe=F )

`# draw Y bars`

for(i in X){ segments3d(x = rep(X[i],2), y = c(0,Y[i]), z=0, lwd=6, col="gold")} # All time bars the same colour

# draw X bars

`for(i in c(10,9,8,7)){segments3d(x = rep(X[i],2), y = 0, z= c(0,Z[i]), lwd=6, col="red")}`

for(i in c(6,5)){segments3d(x = rep(X[i],2), y = 0, z= c(0,Z[i]), lwd=6, col="blue")}

for(i in c(4,3,2,1)){segments3d(x = rep(X[i],2), y = 0, z= c(0,Z[i]), lwd=6, col="green")}

# draw axis

axes3d()

mtext3d(text = "Days", edge = "y+", line =3, col=1 )

mtext3d(text = "%RECIST", edge = "z++", line = 5, col=1 )

Thanks.

Thanks James, I did not think about that. Cheers
