Thanks, balloonplot() is great and gets me really close to what I am after.
However it then brings me to a slightly different problem - I wonder if anyone can suggest where I am going wrong? Again with simplified data ( http://n4.nabble.com/file/n1890724/test-data.txt test-data.txt ): Aug-03 Nov-03 Feb-04 May-04 Aug-04 Row1 1 -1.1 1.2 1.3 -1.4 Row2 3 -3.1 3.2 3.3 -3.4 Row3 5 -5.1 5.2 -5.3 5.4 library(gplots) Read_data=read.table("C:/files/test-data.txt", head = T) number_rows = nrow(Read_data) number_cols = ncol(Read_data) matrix_data = as.matrix(Read_data) row_names = rep(rownames(matrix_data),number_cols) col_names = rep(colnames(matrix_data),number_rows) x11(width=120, height=80) balloonplot(col_names, row_names, abs(matrix_data), dotcolor = c("lightblue", "red")[(c(matrix_data) < 0) + 1], show.margins = FALSE, cum.margins = FALSE, xlab = "", ylab = "", label=T, label.lines= F, colsrt=90, sorted = F, rowmar=3, colmar=2.5,) This gives this graphic: http://n4.nabble.com/file/n1890724/R_upload.jpeg R_upload.jpeg . The data colours go in the "right" places within the grid - i.e. with the correct numbers. However the numbers themselves are mixed up within each row. Transposing the matrix_data within balloonplot() doesn't correct it. Can someone see something simple that I am missing here?
