Hi

I use the command below to draw a heatmap below. However, I would like to label DBA_CONDITION with mediumpurple1 and orange; and label DBA_TISSUE with lightskyblue and orchid1. Could you show me how to do it? Moreover, may I use Sex instead of CONDITION ,and use feather type instead of TISSUE in the figure, and how to do it?

> dba.plotHeatmap(h3k27ac, attributes = DBA_ID, ColAttributes = c(DBA_CONDITION, DBA_TISSUE), colSideCols = c("mediumpurple1", "orange", "lightskyblue", "orchid1"), correlations = FALSE, colScheme = "Blues", scale="row", margin=13)

Best & Many thanks,

Gary

Hi Gary-

Good news/bad news.

The good news is that you can change the labels form Condition and Tissue etc. as follows:

> h3k27ac$config$condition <- "Sex"
> h3k27ac$config$tissue <- "Feather Type"
> plot(h3k27ac)

The bad news is that there isn't an easy way to use different colors for different attributes. I may add this as a feature (by passing in colSideCols as a matrix with a column of colors for each attribute), but it isn't in there now.

Cheers-

Rory
