I'm using ComplexHeatmap to create a heatmap in R. I have recreated a small heatmap here. I can't figure out from the documentation how to adjust the font size for the text on the x-axis.
a = matrix(1:9, nrow = 3, ncol = 3)
rownames(a) = c("alphabet","xylophone","tornado")
colnames(a) = c("c1","c2","c3")
my_heatmap = ComplexHeatmap::Heatmap(
matrix = t(a),
col = RColorBrewer::brewer.pal(9, "RdBu"))
This code produces this:
I want to adjust the font size for the c("alphabet","xylophone","tornado")
text so that it is much smaller. How do I do this?
You can use
row_names_gp
andcolumn_names_gp
to adjust y-axis and x-axis labels, respectively.
