Hello, on using the following code for the following data, the graph I get has 
an x axis where years are mentioned as 2012.5, 2017.5 etc. 

I have the following questions - 
Q1 How can I make the years on x axis as 2011, 2012, 2013, 2014 and so on.. 
Q2 Is there any way to create a small gap between the red and blue bars for 
aesthetic purposes
Q3 Is there anyway to make the text on top of the bars bolder or thicker? 
Thank you

code - 
ymax <- max(graph_text$percentage)ggplot(aes(x=year, y=percentage, color = 
gender, fill=gender), data = graph_text)+  geom_bar(position = 'dodge', 
stat='identity')+  theme_classic()+  geom_text(aes(label = percentage), size = 
4, position = position_dodge(width = 1.1), vjust=-0.2) +   
scale_y_continuous(limits=c(0, 1.4*ymax))
