Coloring different levels in gvis Column Chart

I am trying to use gvis Column chart in R shiny. I have just 1 column with multiple levels and I want to color different levels with different colors. I,m not able to achieve this.

Eg. Data 

     Gender Count
   1 Female   309
   2   Male   280

My Code :

        colGvis <- gvisColumnChart(reqData)

Output :

enter image description here

I want different colors for male and female.

If there are other gvis charts that can do the same, let me know.

Solution

  • googleVis requires you add column roles to your data.frame for aesthetics mapping.

    # Add role column
reqData$Count.style = c('blue','green') 

colGvis<-gvisColumnChart(reqData,
                         xvar = "Gender",
                         yvar = c("Count","Count.style")) # Include in yvar

plot(colGvis)
