I am trying to use heaptmap visualization for my matrix that has 50 rows and 100 columns. I want to improve my heatmap by adding some additional features. The diagram is as follows:
heatmap.2(matrix,Rowv = NA,main = "Health Inverstments per DRG StateWise",xlab = "DRG Definition",
+ ylab = "States",Colv = NA,scale = "column", col = coul1, key = FALSE,
+ margins = c(5,5))
I would like to remove the lines and make the box more visible.
