我想要图1的效果，但是我这个代码出来是图二的效果，纵坐标轴除了我聚的三类，还带有1.0、1.5、2.0、2.5、3.0，如何去掉啊，还有横坐标轴也是这样带有数字，没有出全所有省份，请大佬帮忙看一下，代码如下 plot(scsp2.kmeans<br>
$cluster,pch=scsp2.kmeans$cluster,col=scsp2.kmeans$cluster,xlab="地区",ylab="类别编号",main="聚类结果")<br>
axis(1,at=1:length(scsp2.kmeans$cluster),labels=c("京","津","冀","晋","蒙","辽","吉","黑","沪","苏","浙","皖","闵","赣","鲁","豫","鄂","湘","粤","桂","琼","渝","川","贵","云","藏","陕","甘","青","宁","新"))<br>
axis(2,at=1:3,labels=1:3,cex.axis=0.6)
