I have basic df and I’m trying to add different color for each bar. According to e_color doc we need to provide a vector of colors but it doesn’t work, I’m getting only one color from the vector. Additionally I’d like to rotate by 45dg x axis label but haven’t found any solution yet. Any help with both topics much appreciated.
df <- data.frame( x = c('AAA','BBB','CCC','DDD','EEE','FFF','GGG'), y = c(10,20,30,40,50,60,70) ) my_colors <- brewer.pal(7, "GnBu") df %>% e_chart(x) %>% e_bar(y) %>% e_color(my_colors) %>% e_x_axis(label = list(rotate = 45))
First of all you need to assign your colors to your data frame named
color. Then you can add them by using
"itemStyle". To rotate your labels you should use
axisLabel like this:
library(echarts4r) library(RColorBrewer) my_colors <- brewer.pal(7, "GnBu") df$color <- my_colors df %>% e_chart(x) %>% e_bar(y) %>% e_add("itemStyle", color) %>% e_x_axis(axisLabel = list(rotate = 45))
