Hi all, I'm trying to log chart but with natural looking tick marks. My specifications are very specific -- it must indicate the lowest number's tick as well as the maximum.
I've attached sample code and data for a particular case (and there are a few more like this) where the bottom tickmarks on the chart are not set to where I want them to be and yet they fit in the ylim range. Please, can anyone help? I'm tearing my hair out at this point.. Thanking you in advance, George. # Code below sample<-c(NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, 5525, 5600, 7100, 6124, 6550, 6061, 6950, 6650, 7150, 7275, 8700, 10511, 10399, 10345, 11200, 10200, 11035, 12500, 15750, 14445, 10902, 11500, 8527, 6440, 7140, 7190, 6844, 6750, 6924, 6268, 8010, 7575, 8200, 9240) # Plotting code # Box settings par(bty="l",ps=7,tcl=0.2,mgp=c(0.5,0.2,0),bg="white"); # Make x axis match exactly the data par(xaxs="i",yaxs="r"); # Margins par(mar=c(1.2,1.8,1,1)) # Step 1: Generate logs for the data sampleLog<-log(sample,10) # Step 2: Determine pretty min/max for the data purtee<-pretty(c(sample,pxTarget)) dataMin<-min(sample,na.rm=T)*0.95 dataMax<-max(purtee) # Step 3: Create exponential series t<-exp(seq(log(dataMin),log(dataMax),length=11)) t2<-round(t,-1) t2[t2==0]<-1 # natural looking labels lab<-signif(round(t,-1),2) lab[1]<-signif(lab[1],1) ylimits<-range(log(t2,10)) plot(sampleLog,type='l',xaxt="n",yaxt="n",ylim=ylimits,las=2,ann=FALSE) axis(2,las=2,at=log(lab,10),labels=lab); ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
