Color bar in correlation matrix heatmap

[daamartins]

Dear all

Thank you so much for all the work you have put in setting this great tool. I am wondering whether it is possible to get the color bars for the heatmaps of correlation matrices? I cannot really find them. Is there an equivalent in ggplot that i could use?

Thanks

Hi @daamartins, the R code for the color bar is ggplot2::scale_fill_gradient2(limits = c(-1, 1), na.value = "white") (source). For more details on this scale, see https://ggplot2.tidyverse.org/reference/scale_gradient.html
