Hi ,
I would like to use ggplot2 to plot a matrix as an image.
You can copy paste the following
Data<-matrix(data=rnorm(900,80,20),nrow=30,ncol=30)
lengthOut<-5
Lengths<- 15
library(reshape2)
library(ggplot2)
tdm <- melt(Data)
ggplot(tdm, aes(x = Var2, y = Var1, fill =
factor(value)),levels=seq(0,1,by=0.1)) +
labs(x = "MHz", y = "Threshold", fill = "Duty Cycle") +
geom_raster(alpha=1) +
scale_fill_discrete(h.start=1,breaks=c(20,30,40,50,60,70,80,90),labels=c(20,30,40,50,60,70,80,90),fill="red")
+
scale_x_continuous(expand = c(0, 0)) +
scale_y_continuous(expand = c(0, 0))
# End of code part
What I wanted to do is to print the values
below 20, with an x color
between 20-30, with a y clor
between 30-40, with a z color
and so on....
I would not care now for the color palette.
Any would do.
Could you please help me with that?
Regards
A
