Hi,

Some of Gviz display pars work but some others don't work. Is this a bug?

Example 1:

atrack <- AnnotationTrack(GRanges, name = "ORF", shape = "arrow", 
                  id = ORF$gene,  featureAnnotation  =  "id", 
                  showFeatureId = TRUE,rotation=60)

rotation=0: Numeric scalar. The degree of text rotation for item identifiers.

rotation.title=90: 

While changed rotation.title to 60, title text changed accordingly. However, change rotation to 60, no changes were oberseved for AnnotationId text, i.e. id.

Update: set rotation.item=60 will do what I want. Don't know rotation's role.

Example 2:

e <- makeGRangesFromDataFrame(ORF_expression,keep.extra.columns = TRUE)
strand(e) <- "*"
names(e) <- e$feature
dtrack6 <- DataTrack(e, name="MicroArray")
displayPars(dtrack6) <- list(type="heatmap", ylim=c(-7,8),
                             showSampleNames=TRUE, gradient=c("blue","white","red"),ncolor=100)

By set ylim, I want to fix the heatmap scale. For example, set -7 to blue, white to 0, and 8 to red. But it doesn't work, heatmap bar change one by one, as according to the values in the corresponding panels. By contrast, changing values of gradient and/or ncolor make graph different.

Am I wrong in using these pars or it is a bug?

Thanks.
