How to draw module significance barplot?

plotModuleSignificance(
  geneSignificance, 
  colors, 
  boxplot = FALSE, 
  main = "Gene significance across modules,", 
  ylab = "Gene Significance", ...)

Is it correct to plot the module significance barplot with the code above?

If it is correct, I don't know how should I give 'geneSignificance' and 'colors' value.

Please help me.
