how to change font color in Rcharts Rshiny

[czqiu]

Hello,
I am trying to make different color for chart legend created by Rcharts in Rshiny. For example: I want to make chart legend font and label font in yellow color text instead of the black color text (because I customized my panel in dark grey. The default black color of the font from Rchart makes any font hard to tell). But I could not find how to do it. Any help will be greatly appreciated!

hair_eye = as.data.frame(HairEyeColor) p2 <- nPlot(Freq ~ Hair, group = 'Eye', data = subset(hair_eye, Sex == "Female"), type = 'multiBarChart' ) p2$chart(color = c('brown', 'blue', '#594c26', 'green')) p2 p2$chart(showLegend=TRUE) p4$chart(labelType="value")
