titles lost when combining several tracks #154

Open mgabriel01 opened 3 years ago

Hi,

When several tracks are combined, the title associated to each of them seems to be lost during the process :

library(VariantAnnotation)
library(ggbio)
fl <- system.file("extdata", "ex2.vcf", package="VariantAnnotation")
vcf <- readVcf(fl, "hg19")
my_test1<-autoplot(rowRanges(vcf), layout="karyogram", main="Test1")
my_test2<-autoplot(rowRanges(vcf), layout="karyogram", main="Test2")

tracks(my_test1,my_test2,main="Test3")

ggbio_example

Is there a way to have them back ?

thank you in advance for your answer.

Marc G.

tracks do not support it. It remove titles from all the supplied plots. By this, the arrangement of multiple plots gets easier.

I agree it would be nice to have an option to keep them.
