Hi ALL,
How can I differentiate the area that does not have data or the
data is below the minimum value using color when I plot Contour chart.
For example, my data value range is from 5.0 to 7.5, but I am
interested in the data value from 5.5 to 7.5, so I change levels in the
quant2plot variable. How ever, I want to differentiate the area between
NO data and data value below 5.5.
My script is attached as below, please advise me to implement this
function.
Thanks in advance!
z<-data.matrix(read.table('c:/3029197.txt',sep=','))
x<-1:nrow(z)
y<-1:ncol(z)
SameVal<-0
quant2plot<-c(5.5,5.9,6,6.165,6.29,6.39,6.524,6.9568,7.5)
windows(width=5.5,height=3.5)
par(mar=c(2.3,2.8,2,5),cex.main=1,cex.axis=0.7,cex.lab=1)
filled.contour(x,y,z,
levels=quant2plot,
key.axes=axis(4,quant2plot),
col=c('#8888ff','#00ff70','#00ff00','#afff00','#ffff00','#ffd700','#ffa000','#ff0000'),
plot.title=title(main='My Title')
)
Best Regards,
