How to hide the bar

[lh12565]

Hi, I create a ngchm file to view my heatmap. I want a certain bar to be hidden by default, and then appear after the user checks it (such as "type" as below). How to achieve it? Thanks!

hm <- chmNew('tcga-brca', TCGA.BRCA.ExpressionData)
covariateBar1 <- chmNewCovariate('TP53 Mutation',TCGA.BRCA.TP53MutationData)
hm <- chmAddCovariateBar(hm, 'column', covariateBar1)
covariateBar2 <- chmNewCovariate('type',type)
hm <- chmAddCovariateBar(hm, 'column', covariateBar2)
chmExportToFile(hm,'tcga-brca-covariates.ngchm')

Add display="hidden" to the end of the second chmAddCovariateBar function call.
