I have plotted the dataset below into a stripchart, which gives me the correct graph. However, my x-axis labels are to long to display hortizonal. I would like to display the labels at a 45 degree angle so that all of the labels are displayed. I have used the following text+par code on other graphs and it seems to work fine, but it does not seem to be working on here. I notice when I output the graph to the dataset "mp" then it's value is NULL. Is the stripchart design to be outputted like other graphs? What is the correct syntax to change the position of the x-axis? library(lattice) par(mar = c(7, 4, 4, 2) + .9) mp<-stripchart(InitialScore+FinalScore ~ Scale,data=mpi, vertical=TRUE, method="jitter",pch=1:11,col=1:11, ylab="Scale (0-100)") axis(1, at = mp, labels = FALSE) text(mp,par("usr")[3] - 0.5,srt = 45, adj = 1.1,labels = mpi$Scale,xpd = TRUE) Error in text.default(mp, par("usr")[3] - 0.5, srt = 45, adj = 1.1, labels = mpi$Scale, : 'x' and 'y' lengths differ in text() Dataset: Scale InitialScore FinalScore 1-Pain Severity 75 33 2-Interference 63 35 3-Life Control 20 40 4-AffectiveDistress 65 60 5-Support 33 60 6-Punishing Responses 40 20 7-Solicitous Responses 74 84 8-Distracting Responses 40 90 9-GeneralActivity 20 75 10-Dysfunctional 71 40 11-Interpersonal Distress 60 25 Chris Anderson Data Analyst Medical Affairs wk: 925-677-4870 cell: 707-315-8486 Fax:925-677-4670 This electronic message transmission, including any attachments, contains information which may be confidential, privileged and/or otherwise exempt from disclosure under applicable law.
