如何在水平图中设置不同的x& y标签? [英] how to set different x&y label in levelplot?

问题描述

我正在使用levelplot绘制矩阵.我需要更改x和y标签.当我使用以下代码时，plot看起来不错.但是x和y标签从133到139，而不是133..139 133 ... 139.谁能帮我解决这个问题? (而不是我要绘制的巨大矩阵，我将给出一个样本矩阵)

I am using levelplot to plot a matrix. I need to change x and y labels. When I use the following piece of code, plot looks nice. However x and y labels are from 133 to 139 as opposed to 133..139 133...139. Can anyone help me fix it? (instead of huge matrix i am plotting, I ll give a sample matrix)

library(lattice)
library(RColorBrewer)
m <- matrix(c(0,1,1,2,0,2,1,1,0),6,6)
b <- c(seq(133,139),seq(133,139))
xy.labels <- b
cols <- colorRampPalette(brewer.pal(6, "Spectral"))    
print(levelplot(m, scales = list(labels = xy.labels), col.regions = cols))

推荐答案

我认为您可以简单地使用xlab和ylab选项.

I think you can simply use the xlab and ylab options.

print(levelplot(m, scales = list(labels = xy.labels), col.regions = cols,
            xlab='X Label', ylab='Y Label'))

其他标签可以如下更改

B= c('a','b','c','d','e','f','g', 'a','b','c','d','e','f','g')
XY.labels=B
cols <- colorRampPalette(brewer.pal(6, "Spectral"))    
print(levelplot(m, scales = list(labels = XY.labels), col.regions = cols,
            xlab='X Label', ylab='Y Label'))
