Hi folks~ As yet I've been unable to determine how to expand the distance between the tick marks and tick labels in perspective plots. None of the 'par' setting appear to be applicable to this (including mfg), and placing multiple plots per page results in a bit obscurity, with the tick values overlapping either the tick marks or the axes themselves. The code: main.grid<-layout(matrix(c(1,2,3,4,5,6,7,8),nr=4), widths=c(20,20), heights=c(20,20,20,20)) ticks <- pretty(z) par(mar=c(2,2,2,2)) z <- TPSSLmc x <- (1:nrow(z)+1980) y <- (1:ncol(z)) z0 <- min(z) z <- rbind(z0, cbind(z0, z, z0), z0) x <- c(min(x) - 1e-10, x, max(x) + 1e-10) y <- c(min(y) - 1e-10, y, max(y) + 1e-10) fill <- matrix("seagreen", nr = nrow(z)-1, nc = ncol(z)-1) fill[ , i2 <- c(1,ncol(fill))] <- "grey" fill[i1 <- c(1,nrow(fill)) , ] <- "grey" fcol <- fill zi <- TPSSLmc[-1,-1] + TPSSLmc[ -1,-12] + TPSSLmc[-20,-1] + TPSSLmc[-20,-12] ## / 4 fcol[-i1,-i2] <- heat.colors(30)[cut(zi, quantile(zi, seq(0,1, len = 20)), include.lowest = TRUE)] persp(x, y, z, theta = 140, phi = 20, col = fcol, scale = FALSE, axes=TRUE, ylab="Prey_Age",xlab="",zlab="", nticks=4,ticktype="detailed",expand=17,shade=0.2,cex.axis=1.4,cex.lab=1.5) title("OPERATING MODEL", font.main=3,cex.main=1.5) [plot code repeated 7x for 8 plots per page] dev.off() Thanks so much!!
