How to adjust the axis scales and Label in ggplot2

tidyverse
1

Hi,

I was trying to generate a bar graph through ggplot but I am unable to adjust the scales.
My data difference between two groups are very big so the bar for the smaller count group is very small, almost invisible. so how should I adjust the scales of Y axis so that it is visit. if there is any scope to add zoom bar on scale to drag the bar in ggplot.
How to add labels on the top of the bar in bar graph.

Code and the data has been attached.

Query_detail_Rave2 %>% ggplot(aes(fill = Query_Type, x= Marking Group, y= Query_Count), height = 50, width = 200) +
geom_bar(position= position_dodge(), stat="identity", width = 0.5) + coord_cartesian(ylim = c(0, 500)) +
theme(axis.text.x = element_text(angle = 90, size = 7)) +
geom_text(aes(label = Query_Count), vjust = 1.5, size=3) +
theme(plot.title = element_text(hjust=0.5)) + ylab('Number of Query') +
ggtitle("Number of Query per group")

Hi,

I don't have your data, so I cannot reproduce the graph. Next time, I suggest to make a Reprex, which is great for receiving good responses.

Some suggestions:

  • yscale limits are set in your script. Change upper limit and full bars will become visible
  • change vjust = 1.5 to a negative number to print it above the bar

Hope this brings something you are looking for.

Hi,

I would like continue with this topic.
How to make the label appear only once for every segmented stacked bar. When I am trying to do so the label is appearing for every segment but I need only once at the top of the bar. Please see my data. I am passing the label variable "Query_Closed" for geom_text.

You need to make a dataframe with summed values. I borrowed my code as well, so to pay credits to my source, see the answer here at Stackoverflow

Good luck!
